[PATCH 09/36] drm/gem: fold drm_gem_object_put_unlocked and __drm_gem_object_put()

[Emil Velikov <emil.l.velikov@gmail.com>]

From: Emil Velikov <emil.velikov@collabora.com>

With earlier patch we removed the normal overhead so now we can lift
the helper to the header, folding it __drm_object_put.
