P2P2: Store ID of Device Identity block in network block

Each peer's Device Identity key is unique, while Group SSID, P2P Device
Addresses, and P2P Interface addresses can be randomized. Add support to
map the GO or P2P2 client information of a network block with the
identifier of the Device Identity block. On a P2P Device with the role
of a client, store the ID of the GO in go_dik_id, and on a device with
the role of GO, store the IDs of P2P clients in a list.
