x86/fpu: Always use memcpy_and_pad() in arch_dup_task_struct()
It makes no sense to copy the bytes after sizeof(struct task_struct),
FPU state will be initialized in fpu_clone().
A plain memcpy(dst, src, sizeof(struct task_struct)) should work too,
but "_and_pad" looks safer.
[ mingo: Simplify it a bit more. ]
