Do not try to stop and reset endpoints if USB transfers are aborted
because the HC has been shut down (during suspend/hibernate) or
removed (PCIe card).
In both cases the hardware wont complete the commands, resulting in
timeouts. Instead just do the software part of the abort process.
Unbreak suspend/resume with USB a device connected to xhci(4) as
reported by Fabian Raetz on bugs@.
