drm/amd/pm: Fix a bug in semaphore double-lock
[ Upstream commit 544dcd74b7093ad4befac99b11d90331aa73348e ]
Fix a bug in smu_cmn_send_msg_without_waiting() in
that this function does not need to take the
smu->message_lock mutex in order to send a message
down to the SMU. The mutex is acquired by the
caller of this function instead.
