[media] media: dvb-frontends: constify vb2_ops structure

Browse Source 
Declare vb2_ops structure as const as it is only stored in
the ops field of a vb2_queue structure. This field is of type
const, so vb2_ops structures having same properties can be made
const too.
Done using Coccinelle:

@r1 disable optional_qualifier@
identifier i;
position p;
@@
static struct vb2_ops i@p={...};

@ok1@
identifier r1.i;
position p;
struct sta2x11_vip vip;
struct vb2_queue q;
@@
(
vip.vb_vidq.ops=&i@p
|
q.ops=&i@p
)

@bad@
position p!={r1.p,ok1.p};
identifier r1.i;
@@
i@p

@depends on !bad disable optional_qualifier@
identifier r1.i;

+const
struct vb2_ops i;

File size details of media/dvb-frontends/rtl2832_sdr.o file remains the
same before and after applying the patch.
