mm/slab_common: use SLAB_NO_MERGE instead of negative refcount

Browse source

When CONFIG_MEMCG_KMEM is enabled, we disable cache merging for
KMALLOC_NORMAL caches so they don't end up merged with a cache that uses
ad-hoc __GFP_ACCOUNT when allocating. This was implemented by setting
the refcount to -1, but now we have a proper SLAB_NO_MERGE flag, so use
that instead.
