mm/slab_common.c: work around clang bug #42570

Clang gets rather confused about two variables in the same special
section when one of them is not initialized, leading to an assembler
warning later:

  /tmp/slab_common-18f869.s: Assembler messages:
  /tmp/slab_common-18f869.s:7526: Warning: ignoring changed section attributes for .data..ro_after_init

Adding an initialization to kmalloc_caches is rather silly here
but does avoid the issue.
