[PATCH] slub: add __printf verification to ‘slab_err’:

[Mathieu Malaterre <malat@xxxxxxxxxx>]

__printf is useful to verify format and arguments. Remove the following
warning (with W=1):

  mm/slub.c:721:2: warning: function might be possible candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
