Steven Rostedt 0c667775fe ftrace: Have ftrace_free_filter() WARN and exit if ops is active ...

The ftrace_free_filter() is used to reset the ops filters. But it must be
done if the ops is not currently active (tracing). If it is, it will mess
up the ftrace accounting of what functions are attached and what is not.

WARN and exit the ftrace_free_filter() if the ops is active when it is
called.

Currently, it doesn't seem if anything does this, but it may in the
future.
