problems with QMI dual stack connections from MM - works with qmicli

[Bjørn Mork]

Well, the direct reason is clear from the log: We skip the
CONNECT_STEP_IP_FAMILY_IPV4 step for bearer2+.  So we can connect
multiple IPv6 bearers after the first one.  Just not any IPv4 or
dual-stack.

Still clueless wrt the underlying problem.
