[pve-devel] [PATCH rrd-migration-tool 2/2] migrate nodes: fix handling nonexistent nodes

[Fiona Ebner]

Use the same expression as in the OK(()) branch after the
do_rrd_migration() call. Previously, the presence of a nonexistent
node would lead to a failure:

> Error migrating nodes: Not a directory (os error 20)

That is because the path would have a duplicate node name attached,
for example:
> /var/lib/rrdcached/db/pve2-node/nonexistent/nonexistent

Fixing that alone is not enough, there also was a 'continue' missing
to avoid calling do_rrd_migration() with the old node, i.e. to
actually skip it.
