Eric Sandeen 8e5f820e14 xfs: set format back to extents if xfs_bmap_extents_to_btree 
commit 2c4306f719 upstream.

If xfs_bmap_extents_to_btree fails in a mode where we call
xfs_iroot_realloc(-1) to de-allocate the root, set the
format back to extents.

Otherwise we can assume we can dereference ifp->if_broot
based on the XFS_DINODE_FMT_BTREE format, and crash.
