[PATCH 3/4] wpa_supplicant: Fix creating 6GHz ibss/mesh on 5/6 GHz-capable phys

[Nicolas Cavallari]

If the phy supports both 5 GHz and 6 GHz bands, then 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.
