If there's a gap between records in the rt refcount btree, we ought to
cross-reference the gap with the rtrmap records to make sure that there
aren't any overlapping records for a region that doesn't have any shared
ownership.

Add code to scrub realtime refcount btrees. Similar to the refcount
btree checking code for the data device, we walk the rmap btree for each
refcount record to confirm that the reference counts are correct.
