SLUB: get rid of finish_bootstrap

Its only purpose was to bring some sort of symmetry to sysfs usage when
dealing with bootstrapping per cpu flushing.  Since we do not time out slabs
anymore we have no need to run finish_bootstrap even without sysfs.  Fold it
back into slab_sysfs_init and drop the initcall for the !SYFS case.
