[PATCH] scsi: initio: remove redundant variable rb

[Colin Ian King <colin.i.king@gmail.com>]

The variable rb is being assigned a value but it isn't being
read afterwards. The assignment is redundant and so rb can be
removed.

Cleans up clang scan build warning:
warning: Although the value stored to 'rb' is used in the
enclosing expression, the value is never actually read from
'rb'[deadcode.DeadStores]
