mac80211: join 5GHz checks

Browse source 
Before this commit, devices supporting both 2.4GHz and 5GHz would be
configured for 2.4GHz by default - unless they have VHT capabilities.

With this commit, channel 36 is only set when the frequency is supported.
VHT isn't checked unless that is the case.
