xHCI 1.0: Force Stopped Event(FSE)

xHCI 1.0: Force Stopped Event(FSE)

FSE shall occur on the TD natural boundary. The software ep_ring dequeue pointer
exceed the hardware ep_ring dequeue pointer in these cases of Table-3. As a
result, the event_trb(pointed by hardware dequeue pointer) of the FSE can't be
found in the current TD(pointed by software dequeue pointer). What should we do
is to figured out the FSE case and skip over it.
