The way the current channel survey is implemented in mac80211_hwsim requires for the ACS test cases to be run immediately after the same radio has been on the expected operating band. This was worked around in one of the test cases and errors ignored in couple. Extend this workaround to cover all the test cases. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
