Well the adp driver had a comment that the 0x1D error code means that it
cannot find the command in its execution queue as it already has sent the
command to the target(if I mapped this right between the two drivers).
What looks odd is in the adp driver that move to a higher level of
recovery (i.e., lun reset) if they receive this code, but in the aic94xx
we mark the task TMF_RESP_FUNC_COMPLETE which appears wrong as you found
out with the BUG_ON.
