alarmtimers: Fix time comparison

Browse Source 
commit c9c024b3f3 upstream.

The expiry function compares the timer against current time and does
not expire the timer when the expiry time is >= now. That's wrong. If
the timer is set for now, then it must expire.

Make the condition expiry > now for breaking out the loop.
