signal/nds32: Use force_sig(SIGILL) in do_revisn
As originally committed do_revisn would deliver a siginfo for SIGILL with an si_code composed of random stack contents. That makes no sense and is not something userspace can depend on. So simplify the code and just use "force_sig(SIG_ILL, current)" instead.
