  scripts/kernel-doc warns about using @args: for variadic arguments to
functions. Documentation/doc-guide/kernel-doc.rst says that this should
be written as @...: instead, so update the source code to match that,
preventing the warnings.

trace_events_synth.c:1165: warning: Excess function parameter 'args' description in '__synth_event_gen_cmd_start'
trace_events_synth.c:1714: warning: Excess function parameter 'args' description in 'synth_event_trace'

Thanks, this looks good to me.
