Redo establishment of default SCSI parameters whether or not
we've been compiled for target mode. Unfortunately, the Qlogic
f/w is confused so that if we set all targets to be 'safe' (i.e.,
narrow/async), it will also then report narrow, async if we're
contacted in target mode from that target (acting in initiator
role). D'oh!

Fix ISPCTL_TOGGLE_TMODE to correctly enable the right channel for
dual channel cards. Add some more opcodes. Fix a stupid NULL
pointer bug.
