riscv: reject invalid syscalls below -1
Running "stress-ng --enosys 4 -t 20 -v" showed a large number of kernel oops
with "Unable to handle kernel paging request at virtual address" message. This
happens when enosys stressor starts testing random non-valid syscalls.
I forgot to redirect any syscall below -1 to sys_ni_syscall.
With the patch kernel oops messages are gone while running stress-ng enosys
stressor.
