Please try to avoid introducing more gotos.
If init code below is poll mode specific, let's move it int a separate function.
Then we can have something like:
If (evt_rsrc->enabled)  {
  ...
  ret =  l3fwd_event_resource_setup(...);
  l3fwd_event_service_setup();
 ...
} else 
   ret = l3fwd_poll_resource_setup(...);

...
