Subject: [PATCH v16 06/20] drm/virtio: Replace drm_gem_shmem_free() with drm_gem_object_put()
Prepare virtio_gpu_object_create() to addition of memory shrinker support
by replacing open-coded drm_gem_shmem_free() with drm_gem_object_put() that
decrements GEM refcount to 0, which becomes important for drm-shmem because
it will start to use GEM's refcount during the shmem's BO freeing time in
order to prevent spurious lockdep warning about resv lock ordering vs
fs_reclaim code paths.
