xfs: add online scrub/repair for superblock counters

Teach online scrub and repair how to check and reset the superblock
inode and block counters.  The AG rebuilding functions will need these
to adjust the counts if they need to change as a part of recovering from
corruption.  We must use the repair freeze mechanism to prevent any
other changes while we do this.
