Running watchdog can be a helpful debugging feature on regular
cores, but it's incompatible with nohz_full, since it forces
regular scheduling events. Accordingly, just exit out immediately
from any nohz_full core.
Hm, I don't see why this is needed, for debugging/testing you turn it
on, when you set up for critical operation, you turn it off.
It can be helpful to keep the watchdog running even in production
to help diagnose hard-to-reproduce failures. You just can't have it
running on the nohz_full cores.
