Fix p2p on DFS channel issue: p2p_dfs_chan_enable is NOT enabled on p2p interface

When wpa_supplicant init p2p dev interface, it reads config items from p2p_supplicant_overlay.conf. But when init p2p wlan interface, the config file name is null. We have to save the config items to global p2p data struct.
