[SCSI] aic7xxx: fix ahc_done check SCB_ACTIVE for tagged transactions
The driver only needs to check the SCB_ACTIVE flag if the SCB is not
in the untagged queue.
If the driver is in error recovery, you may end panic'ing on a TUR
that is in the untagged queue.

SCB 3 done'd twice
This patch is included in Adaptec's 6.3.11 driver on their website.
