Log Message:
Make wm(4) watchdog MP-safe. There is almost no influence on performance.

wm(4) does not use ifp->if_watchdog now, that is, it does not touch
ifp->if_timer.
It also uses own callout(wm_tick) as watchdog now. The watchdog uses
per-queue counter to check timeout. So, global lock is not required.
