x86/mce: Fix CPU hotplug and suspend regression related to MCE
Commit 8a25a2fd126c ("cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystem") changed how things are dealt with in the MCE subsystem. Some of the things that got broken due to this are CPU hotplug and suspend/hibernate. MCE uses per_cpu allocations of struct device. So, when a CPU goes offline and comes back online, in order to ensure that we start from a clean slate with respect to the MCE subsystem, zero out the entire per_cpu device structure to 0 before using it.
