[SCSI] aic94xx: fix TMF ascb handling to prevent sequencer panic
This is a particularly nasty bug. The problem is that if any internal
ascb times out, currently we free it even though it's pending at the
sequencer. This results in the sequencer getting terminally confused
and the error message:
BUG:sequencer:dl:no ascb
Being returned when it comes back. The way to fix this is to manage
freeing the ascb from the tasklet completion routine, so that we only
free it when the sequencer actually returns it. The code is also
altered to use on stack completions and transfer variables.
