NFS: Directory page cache pages need to be locked when read
[ Upstream commit 114de38225d9b300f027e2aec9afbb6e0def154b ]
When a NFS directory page cache page is removed from the page cache,
its contents are freed through a call to nfs_readdir_clear_array().
To prevent the removal of the page cache entry until after we've
finished reading it, we must take the page lock.
Fixes: 11de3b11e08c ("NFS: Fix a memory leak in nfs_readdir")
