It appears that the same crash can occur on x86 if park_offline_cpus is set
to 0 during Xen suspend.

This patch implements suspend/resume helpers for the watchdog.

compared to the watchdog period, the domain would be shutdown on resume

These functions may be unimplemented, so check that they exist before
