kprobe/ftrace: fix build error due to bad function definition 

Commit 1a7d0890dd ("kprobe/ftrace: bail out if ftrace was killed")
introduced a bad K&R function definition, which we haven't accepted in a
long long time.

Gcc seems to let it slide, but clang notices with the appropriate error:

  kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all >
   1140 | void kprobe_ftrace_kill()
        |                        ^
        |                         void

but this commit was apparently never in linux-next before it was sent
upstream, so it didn't get the appropriate build test coverage.
