xfs: detect incorrect gaps in rmap btree [v24.5]

Browse source 
Following in the theme of the last two patchsets, this one strengthens
 the rmap btree record checking so that scrub can count the number of
 space records that map to a given owner and that do not map to a given
 owner.  This enables us to determine exclusive ownership of space that
 can't be shared.
