upstream: silence unused-but-set-variable warnings: benchmarks

Origin: debian
Forwarded: https://github.com/igraph/igraph/pull/2640
Last-Update: 2024-06-28

This patch silences a unused-but-set-variable warning as detected
by gcc (Debian 13.3.0-1) in `tests/benchmarks/intersection.c'. It is meant to
be submitted to the upstream maintainer.
