nfs4: Disable file cache to invalidate it

Browse Source 
* When resetting the file cache, use file_cache_disable() to remove
  all pages, instead of calling file_cache_delete().
* Possible fix for #19656.

file_cache_delete doesn't actually delete the VMCache object, so when
file_cache_create() is called the returned file_cache_ref just points
to the same VMCache as before.
