Subject: [PATCH] xfs: Fix termination loop for directory iteration

Directory iteration used wrong position (sizeof wrong structure) for

termination of iteration inside a directory block. Luckily the position

ended up being wrong by just 1 byte and directory entries are larger so

things worked out fine in practice. But fix the problem anyway.
