hostapd: ucode: compute 6 GHz segment centre in iface_freq_info

Browse source 
On 6 GHz there is no HT Operation IE, so a 0 secondary-channel offset made
freq_info() return without a segment centre frequency, leaving wide-channel
switches (80/160/320 MHz) on the stale centre. Pass a null offset for wide
6 GHz channels so the centre is auto-derived.
