wifi-scripts: make scan output fields conditional

Browse Source 
Only print VHT/HE/EHT center frequency and channel width fields
when they are actually populated. This avoids displaying undefined
values for non-6GHz HE results where channel info is derived from
VHT/HT Operation IEs. Also fix center_chan_2 format specifier from
%s to %d.
