Subject: [PATCH][next] scsi: message: fusion: remove redundant pointer hd

The pointer hd is being assigned a value that is not being
read later. The variable is redundant and can be removed.

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