Make netdev_del delete the netdev even when it's in use

To hot-unplug guest and host part of a network device, you do:

    device_del NIC-ID
    netdev_del NETDEV-ID

For PCI devices, device_del merely tells ACPI to unplug the device.
The device goes away for real only after the guest processed the ACPI
unplug event.

You have to wait until then (e.g. by polling info pci) before you can
unplug the netdev.  Not good.

Fix by removing the "in use" check from do_netdev_del().  Deleting a
netdev while it's in use is safe; packets simply get routed to the bit
bucket.

Allow the intercept the RTC IRQ for the HPET legacy mode. Then push

stoppend when there is no IRQ consumer, possibly causing a minor

esp: lower IRQ on soft reset

42f1ced228c9b616cfa2b69846025271618e4ef5 removed irq lowering
during reset. However, for chip reset command and DMA reset signal,
its actually the correct thing to do.

Lower IRQ on soft reset only.
