loopback: Do not detect underruns during initial latency adjustments

Browse source 
Currently module-loopback detects underruns even if sink_input_pop_cb()
was not yet called twice and initial latency adjustments are active.
This leads to unnecessary rewind requests.

This patch delays detecting underruns until the initial adjustments
are done.
