[PATCH 18/29] tools lib traceevent: Use pevent_print_func_field in hrtimer_start handler

Jiri Olsa

The pevent_print_func_field function encompasses all the
functionality used in the hrtimer_start handler. Changing
the handler to use this function.

This also unifies the function field output with the
hrtimer_expire_entry handler.
