History
Justin Hammond f78decb390 drivers/usbhost: Acknowledge xHCI events before walking the ring. 
The event ring was acknowledged after being walked.  An event arriving
during the walk sets the pending bit again, and clearing the bit
afterwards discards it.  Transfers have no timeout, so the transfer that
event belonged to waits forever.

Acknowledge first.  A spurious second pass over an empty ring costs
nothing.
