tests/stp: Make validation of flows before changing of topology.

The change fixes random stp test failure. Accuracy is about 20%. Failed test is following: 2337: STP - flush the fdb and mdb when topology changed In some cases, a validation is executed after topology change and it increase time of stp stabilization. To prevent this, delay which wait validation is added before deleting a port. CC: Tonghao Zhang <[email protected]> Fixes: 427e975 ("tests: Add and improve stp tests.")
