xfs: don't commit sunit/swidth updates to disk if that would cause repair failures
Alex Lyakas discovered that it's possible to mount a filesystem with
sunit/swidth options that will cause a subsequent xfs_repair run to fail
to find the root directory. This series adds some code to strengthen
the kernel's mount option checking to avoid updating the superblock if
this happens.
