9648c344bf util/bridge: drain leftover samples
This prevents sending leftover samples to the client instead of the
RTL0 header required for it to properly control gain.

48c4c2dc40 Remove LO dithering
Means we will probably receive more LO harmonic content but have
better SNR where there is silence.
