xfs: only allow reaping of per-AG blocks in xrep_reap_extents
Now that we've refactored btree cursors to require the caller to pass in a perag structure, there are numerous problems in xrep_reap_extents if it's being called to reap extents for an inode metadata repair. We don't have any repair functions that can do that, so drop the support for now. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com>
