Revert "openvpn plugin: Fix "Dead assignment" warning."

I cherry-picked this patch, but overlooked the fact it relates to
another change (c339d93f) only found in the collectd-5.5 branch.
Reverting, as it results in a compilation error.

This reverts commit b7f9a3c02d885e0fbe8fb7aac5c9a51b5771a9d3.
