xfs: fix dquot scrub loop cancellation
When xchk_quota_item figures out that it needs to terminate the scrub operation, it needs to return some error code to abort the loop, but instead it returns zero and the loop keeps running. Fix this by making it use ECANCELED, and fix the other loop bailout condition check at the bottom too. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Christoph Hellwig <hch@lst.de>
