Add support for NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 feature.
According to the "Hardware crypto acceleration" documentation section,
when set_key() is called with %DISABLE_KEY command, for outgoing frames,
we flush out frames in the queues with the old key; for incoming frames,
no frames will be passed to mac80211 decrypted with the old key due to
rtw_sec_clear_cam().
