[BRIDGE]: Round off STP perodic timers.
Peroidic STP timers don't have to be exact. The hold timer runs at 1HZ, and the hello timer normally runs at 2HZ; save power by aligning it them to next second. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
