[PATCH] nl80211: look for HT/VHT capabilities in beacon's tail

[igor.mitsyanko.os@xxxxxxxxxxxxx]

From: Igor Mitsyanko <igor.mitsyanko.os@xxxxxxxxxxxxx>

There are no HT/VHT capabilities in cfg80211_ap_settings::beacon_ies,
these should be looked for in beacon's tail instead.

This is true for hostapd (at least the one in mainline): it does not
include HT/VHT caps and WLAN_EID_SUPP_RATES into beacon_ies.
But worth noting that there is no clear documentation that I could find
on what IEs could and could not be included into beacon_ies.
