Subject: [PATCH] scsi: initio: remove redundant assignment to pointer scb

The variable scb is assigned a value but it is never read. The assignment
is redundant and can be removed. Also replace the != NULL check with the
more usual non-null check idiom.

Cleans up clang scan build warning:
drivers/scsi/initio.c:1169:9: warning: Although the value stored to 'scb'
is used in the enclosing expression, the value is never actually read
from 'scb' [deadcode.DeadStores]
