frame_relay: Send "Fuil Status" ENQUIRY after link recovers

If we are the 'user' side of FR and a link has just recovered,
we should ensure the next STATUS is for "full status".  This way
we learn about the present DLCs as quickly as possible, saving up
to 10 seconds of further delay in link recovery.
