slab: Update the kmem_cache_create documentation regarding the name parameter



kmem_cache implementations like slub are allowed to merge multiple
caches but only the initial name is preserved. Therefore,
kmem_cache_name() is not guaranteed to return the same pointer passed to
the former function. This patch updates the documentation to make this
clearer.
