[PATCH] arch: x86: kernel: kprobes: functions with definition should not be declared extern

[Emil Goode <emilgoode@gmail.com>]

sparse warns:
arch/x86/kernel/kprobes.c:1489:13: warning: function 'arch_unoptimize_kprobes' with external linkage has definition

This is my first patch which is why I'm sending it here first to see if I'm doing something wrong.
Any advice is greatly appreciated.
