mac80211: Fix Extended Key ID auto activation

Browse source

Only enable Extended Key ID support for drivers which are not supporting
crypto offload and also do not support A-MPDU.

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.
