Log message:
Force openings to 1 for devices that can't do tagged i/o, i.e. more
than 1 i/o active at once. This reduces the chances that concurrent
i/o's for such devices will confuse the device or the adapter code.
It also eliminates a reason for adapter code to maintain its own
queues.
Tweak all drivers that fake INQUIRY results to set the SID_CmdQue
flag, thus continuing to claim to be able to do tagged i/o.
Positive feedback from matthew@ and marco@ for an earlier version.
