xfs: only written file data blocks can be shared
LOLLM noticed that xchk_refcountbt_rmap_check (and its rt equivalent)
will count any rmap owner towards the shared count. However, the only
blocks that can be shared between xfs files are written file data
blocks; and the only blocks that can have single-refcount entries are
COW staging extents. Fix the checking code.
