drm/bochs: Delete an unnecessary check 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 call is not needed. This issue was detected by using the Coccinelle software.
