alloc_thread_stack_node() already populates the task_struct::stack
member except on IA64. The stack pointer is saved and populated again
because IA64 needs it and arch_dup_task_struct() overwrites it.
Allocate thread's stack after task_struct has been duplicated as a
preparation for further changes.
