[RFC v2 95/99] NAN: Indicate if new keys are derived or previous NDP exists

[Andrei Otcheretianski]

Extend nan_ndp_connection_params struct to indicate whether new keys
were derived and whether this is the first NDP established with the
peer.
This is needed by wpa_supplicant to skip STA capabilities and keys
configuration accordingly.
