mm: slub: fix format mismatches in slab_err() callers
Adding __printf(3, 4) to slab_err exposed following: mm/slub.c: In function `check_slab': mm/slub.c:852:4: warning: format `%u' expects argument of type `unsigned int', but argument 4 has type `const char *' [-Wformat=] s->name, page->objects, maxobj); ^ mm/slub.c:852:4: warning: too many arguments for format [-Wformat-extra-args] mm/slub.c:857:4: warning: format `%u' expects argument of type `unsigned int', but argument 4 has type `const char *' [-Wformat=] s->name, page->inuse, page->objects); ^ mm/slub.c:857:4: warning: too many arguments for format [-Wformat-extra-args] mm/slub.c: In function `on_freelist': mm/slub.c:905:4: warning: format `%d' expects argument of type `int', but argument 5 has type `long unsigned int' [-Wformat=] "should be %d", page->objects, max_objects); Fix first two warnings by removing redundant s->name. Fix the last by changing type of max_object from unsigned long to int.
