fibocom: Double-check connection after dialing

Browse Source 
Fibocom's documentation states that we must double-check the connection
is established when setting up an ECM connection. The possible replies -
according to the documentation - are:

  +GTRNDIS: <state>,<cid>,<ip>,<prim. dns>,<sec. dns>
  OK

or

  +GTRNDIS: 0

We just care about the state value which is 1 if everything worked.
