xfs: replace xfs_btree_has_record with a general keyspace scanner
The current implementation of xfs_btree_has_record returns true if it
finds /any/ record within the given range. Unfortunately, that's not
sufficient for scrub. We want to be able to tell if a range of keyspace
for a btree is devoid of records, is totally mapped to records, or is
somewhere in between. By forcing this to be a boolean, we were
generally missing the "in between" case and returning incorrect results.
Fix the API so that we can tell the caller which of those three is the
current state.
