P2P: Restart group formation timer upon receiving new Inv Req

Browse source 
A new Invitation Request might be received on a just started persistent
group if the previous Invitation Response sent isn't received at the
peer (GO of the persistent group). When the peer sends an Invitation
Request again, treat it as start of group formation and restart the
group formation timer at this point of time.
