zte: Delay sending of AT&C0 to disable data carrier detect 

The &C0 can not be send as part of the initial modem init string
since then it return with an error. Also sending it right after seems
to end up in a race condition with the modem init.

So send AT&C0 on both channel after AT+CFUN completed.
