Ammar Faizi 97a5d2e5e3 tracing: Return -EINVAL if WARN_ON(!glob) triggered in event_hist_trigger_parse() 
If `WARN_ON(!glob)` is ever triggered, we will still continue executing
the next lines. This will trigger the more serious problem, a NULL
pointer dereference bug.

Just return -EINVAL if @glob is NULL.
