tracing: Remove leftover FTRACE_ENABLE/DISABLE_MCOUNT enums
The enums for FTRACE_ENABLE_MCOUNT and FTRACE_DISABLE_MCOUNT were used as commands to ftrace_run_update_code(). But these commands were used by the old nasty ftrace daemon that has long been slain. This is a clean up patch to remove the references to these enums and simplify the code a little. Reported-by: Wu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
