svn commit: r284540 - head/sys/dev/isp

New Revision: 284540
URL: https://svnweb.freebsd.org/changeset/base/284540

Log:
  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.
