xfs: set format back to extents if xfs_bmap_extents_to_btree
commit 2c4306f719b083d17df2963bc761777576b8ad1b 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.
