Subject: [PATCH][next] scsi: megaraid: remove redundant assignment to variable retval

The variable retval is being assigned a value that is not being
read afterwards. The assignment is redundant and can be removed.

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