There is actually already a hwsim test case that does this with
WPA-PSK.. In addition, I just tried this with a defconfig build and the
following hostapd.conf file without being able to reproduce.

interface=wlan0
driver=nl80211
hw_mode=g
channel=1
ctrl_interface=/var/run/hostapd
ctrl_interface_group=adm
ssid=test-psk
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
wpa_passphrase=12345678
