device: simplify handling of IP config changes while initializing link

Browse source 
This simplifies commit 31ca7962f8.

We don't need the boolean flags like "queued_ip4_config_pending" to
track whether we received any platform signals while being not yet
initialized in platform (udev, NM_UNMANAGED_PLATFORM_INIT).

In general, as long as the device is NM_UNMANAGED_PLATFORM_INIT,
all platform signals are ignored. And when the device becomes managed,
we schedule anyway an initial config-change.

(cherry picked from commit 18ecc4b4f1)
