Yang Shi 5904c16d22 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.
