Darrick J. Wong 3d2bd2fd5c xfs: verify free block header fields ...

commit de14c5f541 upstream.

Perform basic sanity checking of the directory free block header
fields so that we avoid hanging the system on invalid data.

(Granted that just means that now we shutdown on directory write,
but that seems better than hanging...)
