drm/i915: move i915_buddy slab to direct module init/exit

Browse source 
With the global kmem_cache shrink infrastructure gone there's nothing
special and we can convert them over.

I'm doing this split up into each patch because there's quite a bit of
noise with removing the static global.slab_blocks to just a
slab_blocks.

v2: Make slab static (Jason, 0day)
