USB: serial: quatech2: fix sleep-while-atomic in close commit f09d1886a41e9063b43da493ef0e845ac8afd2fa upstream. The write URB was being killed using the synchronous interface while holding a spin lock in close(). Simply drop the lock and busy-flag update, something which would have been taken care of by the completion handler if the URB was in flight.
