[SCSI] aic7xxx: reset handler selects a wrong command

To transport scsi reset command to device aic7xxx reset handler looks
at the driver's pending_list and searches any proper command. However
the search condition has been inverted: ahc_match_scb() returns TRUE
if a matched command is found. As a result the reset on required
devices did not turn out well, a correctly working neighbour device
may be surprised by the reset. aic7xxx reset handler reports about the
success, but really the original situation is not corrected yet.

Naturally, there's a corresponding problem in the aic79xx driver, so
I've also added the same fix for that.
