drm/i915: move i915_buddy slab to direct module init/exit
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) Reviewed-by: Jason Ekstrand <jason@jlekstrand.net> Cc: Jason Ekstrand <jason@jlekstrand.net> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210727121037.2041102-3-daniel.vetter@ffwll.ch
