nfsd: filecache: use list_lru_walk_node() in nfsd_file_gc()

Browse Source 
list_lru_walk() is only useful when the aim is to remove all elements
from the list_lru.  It will repeatedly visit rotated elements of the
first per-node sublist before proceeding to subsequent sublists.

This patch changes nfsd_file_gc() to use list_lru_walk_node() and
list_lru_count_node() on each NUMA node.
