[SCSI] aic79xx: fix shadowed variables 

OK to just reuse the outer declaration as it is never used again.
drivers/scsi/aic7xxx/aic79xx_pci.c:340:12: warning: symbol 'devconfig' shadows an earlier one
drivers/scsi/aic7xxx/aic79xx_pci.c:299:12: originally declared here

targpcistat is always assigned just before use, remove the inner declaration.
