[media] usb: constify vb2_ops structures
Check for vb2_ops structures that are only stored in the ops field of a
vb2_queue structure. That field is declared const, so vb2_ops structures
that have this property can be declared as const also.
The semantic patch that makes this change is as follows:

identifier i;

static struct vb2_ops i@p = { ... };

e.ops = &i@p;
@bad@
position p != {r.p,ok.p};
