BUILD: log: silence a build warning when threads are disabled

wtarreau · wtarreau · commit 8f9e94ecff7a · 2023-11-22T11:21:07.000+01:00
Building without threads emits two warnings because the proxy pointer is no longer used (only serves for the lock) since 2.9 commit 9a74a6c ("MAJOR: log: introduce log backends"). No backport is needed.
