[PATCH 2/3] scsi: aic7xxx: remove set but not used variable 'ahc'

[yu kuai]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/aic7xxx/aic7xxx_osm.c: In function
âahc_linux_slave_configureâ:
drivers/scsi/aic7xxx/aic7xxx_osm.c:674:20: warning:
variable âahcâ set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
