[PATCH 1/2] x86/ftrace: remove unused modifying_ftrace_code declaration

[Gaosheng Cui]

All uses of modifying_ftrace_code have been removed by
commit 768ae4406a5c ("x86/ftrace: Use text_poke()"),
so remove the declaration, too.

[PATCH 2/2] x86/kprobes: remove unused arch_kprobe_override_function() declaration

[Gaosheng Cui]

All uses of arch_kprobe_override_function() have been removed by
commit 540adea3809f ("error-injection: Separate error-injection
from kprobe"), so remove the declaration, too.
