tracing: Annotate implicit fall through in predicate_parse()

There is a plan to build the kernel with -Wimplicit-fallthrough and
this place in the code produced a warning (W=1).

This commit remove the following warning:

  kernel/trace/trace_events_filter.c:494:8: warning: this statement may fall through [-Wimplicit-fallthrough=]
