lib/crc: Reset fifo underrun reporting for every crc capture

We have tons of issues with crc mismatches, but often by that time
there was already a fifo underrun, which disables further fifo
underrun reporting. Reset fifo underrun reporting before we capture a
crc so that it's easier to figure out why the crc mismatch happened.
