drm/amd/display: Unlock on error path in dm_handle_mst_sideband_msg_ready_event()
[ Upstream commit 38ac4e8385ffb275b1837986ca6c16f26ea028c5 ]
This error path needs to unlock the "aconnector->handle_mst_msg_ready"
mutex before returning.
Fixes: 4f6d9e38c4d2 ("drm/amd/display: Add polling method to handle MST reply packet")
