P2P: Enable SAE-H2E for client when joining a 6 GHz group

Browse source 
Both P2P GO and client always save key_mgmt = WPA_KEY_MGMT_PSK in the
configuration when storing a persistent group. Next time, when a GO is
started as an autonomous GO on a 6 GHz channel, it will change key_mgmt
to SAE and use hash-to-element mechanism, but the P2P client doesn't
change the parameter even if the group it wants to join is operating on
a 6 GHz channel. The P2P connection will be failed due to reason 'reject
due to mismatch with WPA/WPA2'.

Enable SAE-H2E for P2P client in this case.
