Do no try to clear the endpoint, as it if has stalled, if the
USB transfer reported an I/O error.
This is more likely to have no effect apart generating more
errors because when this happens, the device is generally
already physically detached but the *detach() task has not
run yet. So simply return and wait for the device to be
removed like ucom(4) does.
Partially fix an issue reported by RD Thrush rt at thrush.com.
