WPS: Reconnect for a failed data connection when STA_AUTOCONNECT is 0

If "STA_AUTOCONNECT 0" has been used to disable automatic connection on
disconnection event and the driver indicates a failure for the data
connection after successful WPS handshake, it is possible to hit a case
where wpa_s->disconnected is set to 1 and further attempts to connect
shall stop.

While "STA_AUTOCONNECT 0" is used to disable automatic reconnection
attempts in general, this specific WPS case can benefit from trying
again even with that configuration for a short period of time. Extend
the wpa_supplicant re-enable-networks-after-WPS 10 second timeout to
apply for ignoring disabled STA_AUTOCONNECT immediately after a WPS
provisioning step.
