xfs: don't leak EFSBADCRC to userspace
While the verifier routines may return EFSBADCRC when a buffer has a bad CRC, we need to translate that to EFSCORRUPTED so that the higher layers treat the error appropriately and we return a consistent error to userspace. This fixes a xfs/005 regression. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
