[SCSI] aic7xxx: Test opcode, not definition in aicasm:type_check()

This fixes a bug that we treat all sequencer operations as ands and
never do the additional invalid bit checks non-and operations require
because the if () to determine this has an operand which is always
true at the end of the or statement.
