Boris Brezillon 2655948b59 drm/panfrost: Fix a race in panfrost_gem_free_object() 
commit aed44cbeae upstream.

panfrost_gem_shrinker_scan() might purge a BO (release the sgt and
kill the GPU mapping) that's being freed by panfrost_gem_free_object()
if we don't remove the BO from the shrinker list at the beginning of
panfrost_gem_free_object().
