Log:
MFC r284540:
In case of target mode disable at least ISP2532 return invalid zero
ct_rxid value on CTIO completion. Try to workaround that using tag_id
from the CCB, pointed by still valid ct_syshandle.
I don't know whether this is valid fix or dirty hack, but considering that
alternative is indefinitely stuck command -- it worth trying.
