mm, slub: don't create kmalloc-rcl caches with CONFIG_SLUB_TINY
Distinguishing kmalloc(__GFP_RECLAIMABLE) can help against fragmentation
by grouping pages by mobility, but on tiny systems the extra memory
overhead of separate set of kmalloc-rcl caches will probably be worse,
and mobility grouping likely disabled anyway.
Thus with CONFIG_SLUB_TINY, don't create kmalloc-rcl caches and use the
regular ones.
