Subject: afs: Fix afs_edit_dir_remove() to get, not find, block 0

From: David Howells <dhowells at redhat.com>

commit 62d9853aa4ce6e9797b6949804891be14b219752 upstream.

Fix afs_edit_dir_remove() to use afs_dir_get_block() to get block 0 rather
than afs_dir_find_block() as the latter caches the found block in the
afs_dir_iter and may[*] switch out the page it's on if another
afs_dir_find_block() is done.  This parallels what afs_edit_dir_add() does.

[*] There's more than one block per page.
