Jouni Malinen a66d2248a0 tests: Close wlan5 control interface monitor more explicitly
There were couple of common cases where the control interface for the
dynamic wpa_supplicant instance could have been left in attached state
until Python ends up cleaning up the instance. This could result in
issues if many monitor interface events were queued for that attached
socket. Make this less likely to cause issues by explicitly detaching
and closing control interfaces before moving to the next test case.
