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

[yu kuai <yukuai3@huawei.com>]

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

drivers/scsi/aic7xxx/aic7xxx_osm.c: In function ‘ahc_send_async’:
drivers/scsi/aic7xxx/aic7xxx_osm.c:1611:28: warning: variable
‘targ’ set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed. In this case
scsi_transport_target_data() can be removed because of no caller exist.
