cgroup/cpuset: Remove cpuset_do_slab_mem_spread()

Browse Source 
The SLAB allocator has been removed sine 6.8-rc1 [1], so there is no user
with SLAB_MEM_SPREAD and cpuset_do_slab_mem_spread(). Then SLAB_MEM_SPREAD
is marked as unused by [2]. Here we can remove
cpuset_do_slab_mem_spread(). For more details, please check [3].
