[PATCH] hwsim tests: add test for hostapd cli ordering

[Johannes Berg]

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

When the 'SET wpa 2' command is executed last, it seems to somehow
reset parts of the settings, causing hostapd to beacon with the
pairwise cipher suite selector set to 00-0F-AC:0 (none/use-group).
This is not permitted and should be rejected; wpa_supplicant also
cannot connect.
