Antti Palosaari d18ca5b7ce [media] rtl28xxu: fix control message flaws 
Add lock to prevent concurrent access for control message as control
message function uses shared buffer. Without the lock there may be
remote control polling which messes the buffer causing IO errors.
Increase buffer size and add check for maximum supported message
length.
