So, new approach now. Instead of a flag for qmi_device_open(), I
prepared a new qmi_device_set_instance_id() which does all the job. Much
cleaner as no need to define the instance id value when creating the
QmiDevice. qmicli also supports `--device-set-instance-id=X' as well.
It's already in libqmi git master, so you can forget about that previous
branch.

Cheers!
