Subject: [PATCH] modemmanager: fix 'any' iptype setting

When the user requests 'any' as 'iptype', we may get either IPv4 or
IPv6 settings.

Simplify the logic by not requiring any explicit iptype before loading
the method reported by the bearer object for IPv4 and IPv6; just load
the methods right away and setup settings based on those.
