[PATCH] P2P: Notify upper framework on stopping the p2p_find(SEARCH)

This patch notifies the upper framework that an on-going discovery has been stopped. This is useful in cases where
a p2p_find with a timeout value initiated by the upper framework has been finished or when the framework initiated
"p2p_find" is stopped by a "p2p_connect".
