[PATCH] riscv: Fixup wrong clone's arguments define

[guoren at kernel.org]

From: Guo Ren <ren_guo at c-sky.com>

In linux kernel riscv select CLONE_BACKWARDS in
linux/arch/riscv/Kconfig, and in linux/kernel/fork.c:

ifdef CONFIG_CLONE_BACKWARDS
SYSCALL_DEFINE5(clone, unsigned long, clone_flags, unsigned long, newsp,
		 int __user *, parent_tidptr,
		 unsigned long, tls,
		 int __user *, child_tidptr)
elif ...

So we must make the riscv clone-arguments' sequence to be:
  define ARG_FLAGS	0
  define ARG_STACK	1
  define ARG_PTID	2
  define ARG_TLS	3
  define ARG_CTID	4
