Subject: [PATCH] arm: kprobes: fix an old-style function definition

I got a warning when compile kernel:

arch/arm/probes/kprobes/core.c:465:12: warning: old-style function definition [-Wold-style-definition]
  465 | int __init arch_init_kprobes()
      |            ^~~~~~~~~~~~~~~~~

Fix it by add parameter 'void'.
