drm/msm/mdp5: Return error code in mdp5_mixer_release when deadlock is detected
There is a possibility for mdp5_get_global_state to return
-EDEADLK when acquiring the modeset lock, but currently global_state in
mdp5_mixer_release doesn't check for if an error is returned.
To avoid a NULL dereference error, let's have mdp5_mixer_release
check if an error is returned and propagate that error.
