Limit req: unlocking of nodes on complex value errors.
Previously, if there were multiple limits configured, errors in
ngx_http_complex_value() during processing of a non-first limit
resulted in reference count leak in shared memory nodes of already
processed limits. Fix is to explicity unlock relevant nodes, much
like we do when rejecting requests.
