broadband-modem-qmi: work around old Gobi 1K firmware SetDataFormat issue

It seems that really old Gobi 1K firmware (from ~2008) doesn't implement
the SetDataFormat command, and will simply ignore the request without
replying to it.  But the device works just fine if we retry the
QMI port open operation without the SetDataFormat request.

The downside of this is is that on older kernels, the qmi_wwan driver
won't automatically fix up any raw-ip packets it receives, but the
old Gobi devices don't ever send raw-ip packets anyway, so it's not
a problem.
