uqmi: set RAT preference before attach

Set the RAT preference before attaching. This handles cases better,
where a network might be available but not with the preferred RAT.

If RAT is changed to a non-available RAT after attach, QMI does not fail
with missing registration but with failing to establish a PDP session.
