MLK-17348 xhci: Reset endpoint when endpoint is halted
When testing a poor USB disk "Transcend JetFlash XPGMC7W5 ", sometime we
will get TRB TX error during getting string descriptors, then the usb process
aborts due to the context state changed to halted.
Actually when the endpoint context state is halted, we can send reset endpoint
command to put it to stopped state, then set TR dequeue pointer for following
doorbell ring to re-run it. This patch adds this error recovery mechanism.
