udev-node: drop redundant trial of devlink creation

Previously, the devlink was created based on the priority saved in udev
database. So, we needed to reevaluate devlinks after database is saved.

But now the priority is stored in the symlink under /run/udev/links, and
the loop of devlink creation is controlled with the timestamp of the
directory. So, the double evaluation is not necessary anymore.
