I'm hoping you are using only one of those commands at a time..

wpas_ctrl_scan() does this only for a single scan when the SCAN command
explicitly requests this. Once that scan is completed, WPS_PBC or
WPS_PIN command should not be using that special scan handler.

Are you issuing WPS_PBC/WPS_PIN while the previous SCAN TYPE=ONLY
operation is still in progress?

Could you please share wpa_supplicant debug log showing a case where
WPS did not work? (E.g., logcat with wpa_supplicant debug verbosity
increased)

That does not sound like something that should be needed, i.e.,
something else is going wrong here if wpa_s->scan_res_handler is set to
scan_only_handler while you are trying to perform a WPS operation.
