ftrace/x86: Have static function tracing always test for function graph
New updates to the ftrace generic code had ftrace_stub not always being
called when ftrace is off. This causes the static tracer to always save
and restore functions. But it also showed that when function tracing is
running, the function graph tracer can not. We should always check to see
if function graph tracing is running even if the function tracer is running
too. The function tracer code is not the only one that uses the hook to
function mcount.
