net: l2: ppp: Don't attempt reestablish PPP if carrier is down

Browse source 
This commit adds a check to prevent attempting to reestablish
the PPP session if the carrier is down. Without this check,
the PPP FSM attempts and fails to establish a PPP session
twice before giving up. The behavior is not breaking anything,
but it is not desired.
