slub: Allow removal of slab caches during boot
Serialize kmem_cache_create and kmem_cache_destroy using the slub_lock. Only
possible after the use of the slub_lock during dynamic dma creation has been
removed.
Then make sure that the setup of the slab sysfs entries does not race
with kmem_cache_create and kmem_cache destroy.
If a slab cache is removed before we have setup sysfs then simply skip over
the sysfs handling.
