arm64: force_signal_inject: WARN if called from kernel context force_signal_inject() is designed to send a fatal signal to userspace, so WARN if the current pt_regs indicates a kernel context. This can currently happen for the undefined instruction trap, so patch that up so we always BUG() if we didn't have a handler.
