lib/event: update the check of poller returned status

Browse Source 
Per the definition of the poller returned value
 * return 0 to indicate that polling took place but no events were found;
 * return positive to indicate that polling took place and some events were processed;
 * return negative if the poller does not provide spin-wait information.

Have a change to compare whether positive.
