xhci: Turn NEC specific quirk for handling Stop Endpoint errors generic

xHC hosts from several vendors have the same issue where endpoints start
so slowly that a later queued 'Stop Endpoint' command may complete before
endpoint is up and running.

The 'Stop Endpoint' command fails with context state error as the endpoint
still appears as  stopped.

See commit 42b7581 ("usb: xhci: Limit Stop Endpoint retries") for
details
