P2P: Inviting a p2p device from already running persistent p2p go

Below is the command sequence, which creates a problem with current supplicant code if a persistent GO is already running and want to invite a P2P device for the same persistent connection.
Assume X is an entry in the wpa_supplicant.conf file for a persistent connection between P1(GO) and P2(Client).
P1: p2p_group_add persistent=X
P1: p2p_invite <P2P dev addr > persistent=X
In this case, the code in wpas_p2p_invite will try to create another group_interface but will fail as we are already running a persistent GO. The patch will ensure that if we are already running the same GO with same credentials, we should just proceed for an invite without creating an interface.
