NFS: Fix a memory leak in nfs_readdir
We need to ensure that the entries in the nfs_cache_array get cleared when the page is removed from the page cache. To do so, we use the freepage address_space operation. Change nfs_readdir_clear_array to use kmap_atomic(), so that the function can be safely called from all contexts. Finally, modify the cache_page_release helper to call nfs_readdir_clear_array directly, when dealing with an anonymous page from 'uncached_readdir'.
