This patch stops any on-going "p2p_find" on creating an Autonomous GO. This is already taken care in case of invoking a persistent GO. GO as such 
will be advertising via the beacons for other devices to discover. So normally the GO doesn't need to do a p2p_find until and unless it wants to invite
a P2P Client. In case of Invite scenario, logically it is better to do a explicit discover [via user intervention] after the GO is created.  This patch will
help to reduce battery wastage [due to p2p_find operations] in scenarios where user creates a GO and doesn't initiate a connection.
