transceiver: uhd: allow underrun flag to reset during timing alignment

Browse Source 
Allowing the underrun flag to reset will prevent a single event from
causing large jumps in the transmit latency threshold. This should
keep unreasonable timing latencies from occurring (e.g. latencies of
20+ frames).
