config: remove unused NMConfig self argument from nm_config_device_state_*() API

nm_config_device_state_*() always access the file system directly,
they don't cache data in NMConfig. Hence, they don't use the
@self argument.

Maybe those functions don't belong to nm-config.h, anyway. For lack
of a better place they are there.
