usb gadget stack: remove usb_ep_*_buffer(), part 2

This patch removes controller driver infrastructure which supported
the now-removed usb_ep_{alloc,free}_buffer() calls.

As can be seen, many of the implementations of this were broken to
various degrees.  Many didn't properly return dma-coherent mappings;
those which did so were necessarily ugly because of bogosity in the
underlying dma_free_coherent() calls ... which on many platforms
can't be called from the same contexts (notably in_irq) from which
their dma_alloc_coherent() sibling can be called.

The main potential downside of removing this is that gadget drivers
wouldn't have specific knowledge that the controller drivers have:
endpoints that aren't dma-capable don't need any dma mappings at all.

Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers.
This patch just removes the interface and its users; later patches will
remove controller driver support.

  - This interface is invariably not implemented correctly in the
    controller drivers (e.g. using dma pools, a mechanism which
    post-dates the interface by several years).

  - At this point no gadget driver really *needs* to use it.  In
    current kernels, any driver that needs such a mechanism could
    allocate a dma pool themselves.

Removing this interface is thus a simplification and improvement.

This patch updates some of the documentation about DMA buffer management

 - Most drivers should *avoid* the dma-coherent allocators.  There are

   DMA" capability through a driver stack.  This is easy, everything
   already avoids highmem.  But it'd be nice if x86_32 systems with much

usb: free DMA mappings if enqueue fails

This patch releases DMA resources if enqueue fails in the HCD.

Linux had this bug ever since we converted from virt_to_bus for 2.4.
It is difficult to hit. A user would need a significant memory pressure
or some other unusual condition.

It was reported to me by IBM. They ran a management application for
RSA II adapters which sent Bulk requests to an Interrupt endpoint.
Submissions got rejected by HCD due to an invalid interval value
and the swiotlb pool became depleted in the matter of hours.

We fixed the invalid interval issue in devio.c separately, but this
seems to be a bug worth fixing as well.

synchronization in usb_serial_put

I think there is a race between usb_serial_put() and
usb_serial_get_by_index() (and get_free_serial()) with regards
to handling the serial port refcount.

usb_serial_get_by_index() gets a reference on the serial port under
table_lock while return_serial releases all the returned ports
from the table under the same lock.  However, the table_lock is not
taken around the call to kref_put, theoretically allowing to sneak
in and grab a reference after kref_put has already determined that

Okay, from this it looks like there's a problem in the option.c serial
driver.  Glancing at the code, it's obvious why: The thing totally
