drivers/scsi: remove unnecessary NULL test
At the point where cmnd is initialized, it is tested for NULL, so it
doesn't have to be tested again here.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@match exists@
expression x, E;
identifier fld;
@@
* x->fld
... when != \(x = E\|&x\)
* x == NULL
// </smpl>
