Steven Price d0a396083e serial: core: Don't drop port_mutex in serial_core_remove_one_port 
Commit 84a9582fd203 ("serial: core: Start managing serial controllers to
enable runtime PM") required the caller to hold port_mutex rather than
taking it locally. However the mutex_unlock() call wasn't removed
causing the mutex to be dropped unexpectly. Remove the call to
mutex_unlock() (and fix up the early return) to restore correct
behaviour.
