DFS: Make sure center frequency is always initialized for VHT 

This seemed to be fine on most code paths, but the code was complex
enough to make the analysis difficult (and a bit too much for static
analyzers). There is no harm in forcing these parameters to be
initialized, so do that to make sure they cannot be left uninitialized.
