x86/ftrace: Add one more ENDPROC annotation 

When ORC support was added for the ftrace_64.S code, an ENDPROC
for function_hook() was missed. This results in the following warning:

  arch/x86/kernel/ftrace_64.o: warning: objtool: .entry.text+0x0: unreachable instruction

Fixes: e2ac83d74a ("x86/ftrace: Fix ORC unwinding from ftrace handlers")
