USB: xhci: Performance - move interrupt handlers into xhci-ring.c
Most of the work for interrupt handling is done in xhci-ring.c, so it makes
sense to move the functions that are first called when an interrupt happens
(xhci_irq() or xhci_msi_irq()) into xhci-ring.c, so that the compiler can better
optimize them.
Shorten some lines to make it pass checkpatch.
