workqueue: drop "std" from cpu_std_worker_pools and for_each_std_worker_pool()

Browse Source 
All per-cpu pools are standard, so there's no need to use both "cpu"
and "std" and for_each_std_worker_pool() is confusing in that it can
be used only for per-cpu pools.

* s/cpu_std_worker_pools/cpu_worker_pools/

* s/for_each_std_worker_pool()/for_each_cpu_worker_pool()/
