cfg80211: allow connect keys only with default (TX) key

There's no point in allowing connect keys when one of them
isn't also configured as the TX key, it would just confuse
drivers and probably cause them to pick something for TX.
Disallow this confusing and erroneous configuration.

As wpa_supplicant will always send NL80211_ATTR_KEYS, even
when there are no keys inside, allow that and treat it as
though the attribute isn't present at all.
