wifi: Fix for connection between GO and p2p device

When GO sends an invitation request to the p2p device without
persistent profile, GO gets an invitation result=8 which means
unknown group, when GO receives invitation result 8, its tries
to remove persistent profile of the client but it will not be able
find the profile so it does continue with sending the invitation
so the connection fails. To address this, ignore if there are no
persistent profiles found for the client and continue with sending
the Invitation request to the client to make connection succesful
connection. As GO has single profile saved unlike client which
saves multiple profiles of GO.

Wifi: Fix for connection failure between third client and GC.

When third device sends a connection request to the group client, the
existing connection is terminating and also the ongoing connection not
successful.Currently as there is  no use case where third device is
connecting to GC,and the existing onnection getting terminated.This
is addressed by ignoring the new connection request from third client
to GC and the existing connection is intact.
