xfs: check for fragments when full-extent sharing matches

LOLLM noticed that xchk_refcountbt_process_rmap_fragments returns early
if there are enough rmap records that overlap the space referenced by a
refcountbt record to match the refcount in that refcountbt record.
Unfortunately, it never checks the fragment list in this case, so it
won't find the discrepancy between the rmap and refcount btrees.
