V4L/DVB: cx2341x: Remove temporal filter control restriction
Since the change that stops the CX23415/6 firmware-intiiated secondary stream appears to fix the temporal filter, it's now fully re-enabled for all capture resolutions.

temporal filter is that it works well with full resolution

capturing, but not when the capture window is scaled (the

filter introduces a ghosting effect). So if the capture

window is scaled, then force the filter to 0.

For full resolution the filter really improves the video
