Division by Zero whilst switching between Presets #868

Windows 10, SDRangel v6.10.1 Switched between presets, each having a single Broadcast FM decoder. Approx. one out of 20 times the app closes with a division by zero. Seems to be independent of the selected demods, did also happen with NFM and DSD demods in preset.

Logically you cannot read or write from a FIFO of size 0 so read/write operations should check size and return immediately if zero.
