[SCSI] aic79xx: Invalid Sequencer interrupt occured

On certain systems the driver seems to hit upon some
"scsi0: Invalid Sequencer interrupt occurred." problem and dumps card state.
According to Adaptec engineers this message is harmless. So as not to
confuse user we can as well disable the internal card state dump and
just print out the message itself.
