As it turns out, WPS does not work if a network configuration in
wpa_supplicant has the flag `mode=2` (access point mode) set:

"""
ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
	ssid="AP"
	key_mgmt=NONE
	mode=2
	id_str="ap"
}
"""

Setting mode=2 for a network and having ap_scan=1 (default) means if no
APs matching to the currently enabled networks are found, a new network
 (IBSS or AP mode operation) may be initialized (if configured).

So, WPS does not work if the interface is operating in AP mode. I
wonder, if this is a desired behavior? At least, wpa_supplicant does
not complain, but prints "WPS-PBC-ACTIVE", but no messages are
following, until "WPS-TIMEOUT".
