xfs: clear BAD_SUMMARY if unmounting an unhealthy filesystem

Source kernel commit: 519841c207de9926418d2f39e162097088478781

If we know the filesystem metadata isn't healthy during unmount, we want
to encourage the administrator to run xfs_repair right away.  We can't
do this if BAD_SUMMARY will cause an unclean log unmount to force
summary recalculation, so turn it off if the fs is bad.
