P2PS: Allow P2P_CONNECT command for P2PS connection with/without PIN

This allows using P2PS config method with or without PIN for connection.
wpa_supplicant should internally handle the default PIN "12345670" and
shall also allow connection irrespective of PIN used in P2P_CONNECT.

For example,
 1. P2P_CONNECT 02:2a:fb:22:22:33 p2ps
 2. P2P_CONNECT 02:2a:fb:22:22:33 xxxxxxxx p2ps
Where the second one is maintained for backwards compatibility.
