commit e16d10ade6204a2f896eb872fb5075bec8e5164f

    PPP: remove unused and confusing return values other than ERR_OK for 
ppp_connect and ppp_listen
    
    User should not use ppp_connect or ppp_listen return value to retry
    later, it must wait for the callback to be called. This is primarily
    done this way to have a consistent behavior with and without the
    holdoff feature.
    
    Remove returned error value from PPP link level API connect and listen
    callbacks because we are not using them anymore, then make ppp_connect
    or ppp_listen to always return ERR_OK, thus we are not breaking the PPP
    user API.
    
    We don't need the return code here, all PPP link level drivers can't
    fail at all (e.g. PPPoS) or retry if necessary (PPPoE and PPPoL2TP).
