media: imon: grab lock earlier in imon_ir_change_protocol()
Move mutex_trylock() in imon_ir_change_protocol() to the beginning,
for memcpy() which modifies ictx->usb_tx_buf should be protected by
ictx->lock.
Also, verify at the beginning of send_packet() that ictx->lock is held
in case send_packet() is by error called from imon_ir_change_protocol()
when mutex_trylock() failed due to concurrent requests.
