P2PS: Do not remove pending interface on p2p_stop_find

The pending interface created during provision discovery should
not be removed on stopping p2p_find. This pending interface has
to be used after completing GO negotiation. Earlier the pending
interface is created just before GO negotiation so there was no
problem.
