kernel/kthread.c: partial revert of 81c98869faa5 ("kthread: ensure locality of task_struct allocations")

After discussions with Tejun, we don't want to spread the use of
cpu_to_mem() (and thus knowledge of allocators/NUMA topology details) into
callers, but would rather ensure the callees correctly handle memoryless
nodes.  With the previous patches ("topology: add support for
node_to_mem_node() to determine the fallback node" and "slub: fallback to
node_to_mem_node() node if allocating on memoryless node") adding and
using node_to_mem_node(), we can safely undo part of the change to the
kthread logic from 81c98869faa5.
