This looks like problem when wpa_supplicant do not talk to correct
kernel socket when cfg80211 module was removed and then loaded again.
This can happen when you remove wireless device driver using
modprobe -r  i.e:

modprobe -r rt2800usb
modprobe rt2800pci

This problem is fixed in current version of wpa_supplicant or maybe
in kernel.

"systemctl restart wpa_supplicant.service" recovers from bad state.
