With find_multipaths enabled, there can be non-blacklisted paths that
are not supposed to be part of any multipath device. To make sure that
check_path doesn't keep checking them, this patch marks paths which are
fully initialized. Only uninitialized paths are checked, if they don't
belong to a multipath device.
