RAS: Fix return value from show_trace()
Documentation/filesystems/seq_file.rst describes the possible return
values from a "show()" function used by single_open().
show_trace() returns the value of "trace_count". This could be
interpreted as "SEQ_SKIP", or just confuse the calling function.
Change to just return "0" to avoid confusing anyone reading this code
and possibly using as a template. Reading "daemon_active" was never
an intended use case.
