xfs_repair: stop using XFS_BTREE_MAXLEVELS

Use the precomputed per-btree-type max height values.

[sandeen: note that >= changes to > here; The maximal value is
fine, but with the precomputed value specific to this filesystem,
our new limit is the actual acceptable max, vs. XFS_BTREE_MAXLEVELS
which was an absolute design max and was larger than most filesystems
could create.]
