Only enable Extended Key ID support for drivers which are not supporting

While any driver using SW crypto from mac80211 is generally able to also
support Extended Key ID these drivers are likely to mix keyIDs in
AMPDUs when rekeying.
According to IEEE 802.11-2016 "9.7.3 A-MPDU contents" this is not
allowed.
I applied this (with some changes), but please resend the other patch as
two separate patches to mac80211/hwsim.
I've just dropped you the updated patch for hwsim Extended Key ID
support. That's kind of critical for the attempt to get Extended Key ID
support merged in hostapd/wpa_supplicant.
The patch to allow ptk0 rekeys with hwsim should follow soon. (The PTK0
rekey patches I have for hostapd/wpa_supplicant still need serious work
anyhow and are far away to be ready for merge.)
