instead of using two static calls you can use the new:

   trace_call__riscv_tlb_flush_path()

That is to be used instead of the trace_<event>() if it's behind a
trace_<event>_enabled() check. That is because the
trace_call__<event>() will always trigger the trace event logic because
it should only be called when the trace event was enabled.
