Cleanup SDR usage when no channel, but full spectrum is used.

Browse Source 
Radio and TV uses full spectrum, so they set channels to 0, this will
define a center frequency only. The spectrum is then processed by the
applications and not by libsdr.

The sample rate must be a factor of 1e9, so that time stamps work
and signal has no gaps/glitchs.
