fs: nfs: return per memcg count for xattr shrinkers
The list_lru_count() returns the pre node count, but the new xattr
shrinkers are memcg aware, so the shrinkers should return per memcg
count by calling list_lru_shrink_count() instead. Otherwise over-shrink
might be experienced. The problem was spotted by visual code
inspection.
