lockup_detector: Convert cpu notifier to return encapsulate errno value

Browse source

By the commit e6bde73b07
("cpu-hotplug: return better errno on cpu hotplug failure"),
the cpu notifier can return encapsulate errno value, resulting
in more meaningful error codes for CPU hotplug failures.

This converts the cpu notifier to return encapsulate errno value
for the lockup_detector as well.
