[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. Signed-off-by: Vasily Averin <vvs@sw.ru> Naturally, there's a corresponding problem in the aic79xx driver, so I've also added the same fix for that.
