Commit c780d01cf1 ("media: vb2: vb2_core_queue_init(): sanity check lock
and wait_prepare/finish") added a sanity check to ensure that if there are
no wait_prepare/finish callbacks set by the driver, then the vb2_queue lock
must be set, since otherwise the vb2 core cannot do correct locking.
The rtl2832_sdr.c triggered this warning: it turns out that while the
driver does set this lock, it sets it too late. So move it up to before
the vb2_queue_init() call.
