Subject: [PATCH] scsi: megaraid_mbox: remove redundant initialization of pointer mbox

From: Colin Ian King <colin.king@...onical.com>

The pointer mbox is being initialized with a value that is
never read and it is being updated later with a new value.  The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
