 itimer: Fix mistaken overflow prevention in overrun counting.
 
 itimer_transition just returns the new number of overruns, doesn't
 add to an existing number; it's the caller who must add to the
 existing number, and avoid arithmetic overflow in that addition.
 (Should maybe push the addition into itimer_transition but that
 requires a little more work -- also it should maybe saturate at
 DELAYTIMER_MAX rather than INT_MAX.)
 
 While here, fix another arithmetic overflow in overrun counting in
 ptimer_intr.
