This test fails randomly, and it appears to be due to excessive scanning. Historically most autotests start a dbus scan right away. The problem is that most likely a periodic scan is already ongoing, meaning the dbus scan gets queued. If a Connect() call comes in (which it always does), the dbus scan gets delayed and will trigger once connected, at a time the test is not expecting. This can cause problems with any assumed timing as well as offchannel frames. This patch removes the explicit DBus scanning and instead uses scan_if_needed with get_ordered_networks. The 'all_blacklisted_test' was also modified to wait for scanning to complete after failing to connect to all BSS's. This lets all the networks fully come up (after being blocked by hwsim) and appear in scan results.
