hwtimer/hwtimer32: Remove task_resched_if_needed from watchdog help

Browse Source 
Remove task_resched_if_needed, since we don't do any task scheduling
modifications. Just return instead.

This makes it work on F0 as well, where we don't have task_resched_if_needed

BUG=None
TEST=With series, see watchdog help work on any veyron
BRANCH=veyron
