- Remove CONFIG_SLAB ifdefs. The code works just fine with both allocators.
- Reset metada offsets if metadata doesn't fit. Otherwise kasan_metadata_size()
will give us the wrong results.

For KASAN builds:
- switch SLUB allocator to using stackdepot instead of storing the
allocation/deallocation stacks in the objects;
- define SLAB_RED_ZONE, SLAB_POISON, SLAB_STORE_USER to zero,
effectively disabling these debug features, as they're redundant in
the presence of KASAN;
