ftrace: Fix compilation warning about control_ops_free
With CONFIG_DYNAMIC_FTRACE=n, I see a warning:
kernel/trace/ftrace.c:240:13: warning: 'control_ops_free' defined but not used
static void control_ops_free(struct ftrace_ops *ops)
^
Move that function around to an already existing #ifdef
CONFIG_DYNAMIC_FTRACE block as the function is used solely from the
dynamic function tracing functions.
