Johannes Berg 3691db26f7 tests: Add test reconnecting on assoc failure 
Add a test that drops the authentication frame, so that
hostapd thinks the station is unknown, and then sends one
by itself, so the station thinks it's associated. This
tests mostly the kernel's capability to recover from this
scenario.
