tests: Force p2p_find in p2p_service_discovery_fragmentation

It was possible for this test case to fail if P2P_FLUSH was issued
during a search scan and that scan adding back the peer. Avoid this by
forcing p2p_find to be started regardless of the current P2P peer table
contents for each round of service discovery.
