Quiet -Wmaybe-uninitialized warnings from gcc

I think these were false positives, as the accesses were all inside
"if (cs->verbose)" checks, matching the initialization case for them,
but this makes gcc stop warning.

xlsclients.c:531:13: warning: ‘wm_class’ may be used uninitialized [-Wmaybe-uninitialized]
  531 |             free(wm_class);
