xfs: ensure that all metadata and data blocks are not cow staging extentsscrub-detect-refcount-gaps-6.4_2023-04-12scrub-detect-refcount-gaps-6.4_2023-04-11

Make sure that all filesystem metadata blocks and file data blocks are
not also marked as CoW staging extents.  The extra checking added here
was inspired by an actual VM host filesystem corruption incident due to
bugs in the CoW handling of 4.x kernels.
