xfs: strengthen the "is cow staging" helpers in scrub
LOLLM pointed out a bug in both of the refcount scrub predicates that
determine if a range of blocks is marked as CoW staging in the btree.
While it compares blockcount < len, this isn't enough to determine that
the CoW staging record is at least as large as the range passed into the
helper. Fix both of them.
