Subject: [PATCH 2/4] drivers/scsi/bfa/bfa_svc.c: remove unneeded structure

From: Julia Lawall <Julia.Lawall@...6.fr>

Delete a local structure that is only used to be initialized by memset.

A semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier x,i;
@@

{
... when any
-struct i x;
<+... when != x
- memset(&x,...);
...+>
}
// </smpl>
