staging: rtl8192e: Unlock mutex for one line in rtllib_stop_protocol()
The following command uses the mutex ieee->wx_mutex:
cancel_delayed_work_sync(&ieee->associate_retry_wq)
Therefore it cannot be canceled with ieee->wx_mutex locked.
rtllib_stop_protocol() is always called with ieee->wx_mutex locked so
according line can be unlocked.
