ftrace: Have cached module filters be an active filter
When a module filter is added to set_ftrace_filter, if the module is not loaded, it is cached. This should be considered an active filter, and function tracing should be filtered by this. That is, if a cached module filter is the only filter set, then no function tracing should be happening, as all the functions available will be filtered out. This makes sense, as the reason to add a cached module filter, is to trace the module when you load it. There shouldn't be any other tracing happening until then.
