6 GHz: Fix opclasses mapping in ieee80211_freq_to_channel_ext()

Browse source 
Previously only primary channel number used to calculate 6GHz operating
class in ieee80211_freq_to_channel_ext() and it is always giving 131
operating class. Fix this by mapping operating class using chanwidth and
sec_channel also.

This is needed to avoid OCV failures on the 6 GHz band when the channel
width is larger than 20 MHz.
