drm/gem: fix not to assign error value to gem name
commit 2e07fb229396f99fc173d8612f0f83ea9de0341b upstream.
If idr_alloc() is failed, obj->name can be error value. Also
it cleans up duplicated flink processing code.
This regression has been introduced in
commit 2e928815c1886fe628ed54623aa98d0889cf5509
