Since "57cebc4 mtd: ubi: Fix scrubbing during attach" we make sure
that the wear level worker does not start too early. However, now
there are cases when the worker starts too late. When a ubi image is
freshly written a volume may be autoresized. This has to be done
after the wear level worker is started because otherwise the initial
fastmap update will not be able to find any anchor PEBs.
