xfs: pass runtime errors from xrep_iunlink_mark_ondisk_rec up to callers

LOLLM points out that the only error that xrep_iunlink_mark_ondisk_rec
returns is ENOMEM, but we ignore that, and can end up writing a garbage
AGI based on incomplete information.  We shouldn't do that, though here
we must be screen out EFSCORRUPTED/EFSBASDCRC because we haven't
checked the inobt yet.
