[PATCH 2/2] nl80211: change vif type to P2P_CLI upon p2p authentication

[Eliad Peller]

Currently, wpa_driver_nl80211_authenticate() changes the
interface type to station. however, in case of p2p, we
need to change the interface type to p2p_cli.

Add p2p field to the authentication params, and
consider it for choosing the correct interface type.
