Fix creating 6 GHz IBSS/mesh on 5/6 GHz-capable PHYs

Browse source 
If the PHY supports both 5 GHz and 6 GHz bands, there will be two
different struct hostapd_hw_modes with mode HOSTAPD_MODE_IEEE80211A,
one for each band, with potentially different capabilities.

Check that the struct hostapd_hw_modes actually contains the frequency
before selecting it.
