[SCSI] mpt2sas: take size of pointed value, not pointer

Sizeof a pointer-typed expression returns the size of the pointer, not that
of the pointed data.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

expression *e;
type T;
identifier f;
@@

f(...,(T)e,...,
-sizeof(e)
+sizeof(*e)
,...)
// </smpl>
