scsi: initio: Remove redundant variable 'rb'
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]
