scsi: aic7xxx: Fix 'amount_xferred' set but not used issue
'amount_xferred' is used, but only in certain circumstances. Place
the same stipulations on the defining/allocating of 'amount_xferred'
as is placed when using it.
We've been careful not to change any of the ordering semantics here.
Fixes the following W=1 kernel build warning(s):
drivers/scsi/aic7xxx/aic79xx_osm.c: In function ‘ahd_done’:
drivers/scsi/aic7xxx/aic79xx_osm.c:1796:12: warning: variable ‘amount_xferred’ set but not used [-Wunused-but-set-variable]
