AP MLD: Do not store per-supplicant AP MLD MAC address information

Browse source 
There is no need to store the AP MLD MAC address within per-supplicant
data structure in struct wpa_state_machine since that MLD MAC address is
available from the generic authenticator data in struct
wpa_authenticator.
