wlan: Ignore set auto power save command in non-authenticated state.

Device should not enter power save mode until pairwise and group key
handshake is done. Otherwise it might introduce delay during EAPOL key
exchange(Pairwise and Group key). To avoid this accept enter bmps
command only in authenticated state.
