Hannes Reinecke 534ef056db [SCSI] aic79xx: check for non-NULL scb in ahd_handle_nonpkt_busfree
When removing several devices aic79xx will occasionally Oops
in ahd_handle_nonpkt_busfree during rescan. Looking at the
code I found that we're indeed not checking if the scb in
question is NULL. So check for it before accessing it.
