xfs: check absolute maximum nlevels for each btree type

Add code for all five btree types so that we can compute the absolute
maximum possible btree height for each btree type, and then check that
none of them exceed XFS_BTREE_CUR_ZONE_MAXLEVELS.  The code to do the
actual checking is a little excessive, but it sets us up for per-type
cursor zones in the next patch.
