astyle fix

A bug was detected when the uint8_t SUBGRF_GetFskBandwidthRegValue( uint32_t bandwidth )
is called and the bandwith argument has a value of 0.

Comparing the code to the STMCubeWL 1.1 we can see that an if statement is missing to
address the condition where bandwith is equal to 0.

Added the if statement to the radio driver to account for this edge case.

Improvment to support extensive tests
