drm/msm: Delete unnecessary checks before drm_gem_object_unreference_unlocked()
The drm_gem_object_unreference_unlocked() function tests whether
its argument is NULL and then returns immediately.
Thus the test around the calls is not needed.
This issue was detected by using the Coccinelle software.
