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:

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