Hwsim is not using HW crypto offload and can correctly rekey PTK keys.
Set NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to not trigger workarounds.

Also allow Extended Key ID to be used with hwsim, regardless that the
driver A-MPDU aggregation is violating IEEE 802.11 and can aggregate
MPDUs using different key IDs into one A-MPDU.

Hwsim can only communicate with other hwsim cards and itself is able to
handle the non-standard A-MPDUs on Rx.
