xfs: handle non-inode owners for rtrmap record checking

Browse source

LOLLM noticed that two helper functions in the rtrmapbt scrub code don't
actually handle non-inode owners correctly -- CoW staging extents and
rgsuperblock extents are not shareable, but they are mergeable.  Fix
these two helpers.
