tests: Use more enforced order for the RSN IBSS steps

test_ibss_rsn has been failing pretty frequently due to various issues
in getting all connections up. Try to address this initially by avoiding
concurrent operations and explicitly waiting for 4-way handshake
completion before testing data connection. Once this test case is
workign more robustly, a more difficult case with concurrent operations
can be added as a separate test case.
