[PATCH 15/17] tests: test_ap_open_poll_sta_no_ack: fix mgmt-rx race

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

We need to wait for the MGMT-RX event before disabling
ext_mgmt_frame_handling again, otherwise we might be
disabling it and hostapd only receives the deauth frame
after we already disable it, defeating the purpose of
the test.
