Apply polarization parameters even if a satellite number is not provided.
The polarization is fetched from struct dvb_v5_fe_parms directly and not from
the
parameter DTV_POLARIZATION.
Since DTV_VOLTAGE and DTV_TONE are set according the polarization, those
parameters
are removed from the props structures in dvb-v5-std.c.
