V4L/DVB (9805): cx18: Port fix for raw/sliced VBI mixup from ivtv and cx25840
This is a port of the fixes Hans Verkuil made for ivtv/cx25840: The service_set field was used to determine whether raw or sliced VBI was desired. This is incorrect since it is perfectly valid to select sliced VBI with a service_set of 0. Instead the driver should check on VIDIOC_S_FMT whether the type field matches the raw or sliced VBI type. Updated the cx18 driver accordingly, including an additional check in cx18_start_v4l2_encode_stream() that didn't exist in ivtv.
