slab: remove unused SL_CPU slab_stat_type

Browse source

Since the removal of the per-cpu slab in commit 32c894c727 ("slab:
remove struct kmem_cache_cpu"), show_slab_objects() no longer has a
branch handling SO_CPU, so cpu_slabs_show() always produces "0".

Emit "0\n" directly instead, matching the sibling cpu_partial and
slabs_cpu_partial stubs, and remove the now-unused SO_CPU macro and
SL_CPU enum value.

No functional change intended; the cpu_slabs sysfs attribute continues
to read 0.
