V4L/DVB: Allow to enable TS continuity and TEI check on loaded module

Current dvb_demux_tscheck processing doesn't allow to enable check on loaded
module. dvb_demux_tscheck can be enabled only when loading module (
dvb_dmx_init should be called to enable dvb_demux_tscheck ). This patch fix
this issue.
