[PATCH 18/18] plugins: fix -Werror=maybe-uninitialized false-positive

[Alex Bennée]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

../contrib/plugins/cache.c:638:9: error: ‘l2_cache’ may be used uninitialized 
[-Werror=maybe-uninitialized]
  638 |         append_stats_line(rep, l1_dmem_accesses, l1_dmisses,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Is a false-positive, since cores > 1, so the variable is set in the
above loop.
