x86: re-enable MCE on secondary CPUS after suspend/resume
Impact: fix disabled MCE after resume Don't prevent multiple initialization of MCEs. Back from early prehistory mcheck_init() has a reentry check. Presumably that was needed in very old kernels to prevent it entering twice. But as Andreas points out this prevents CPU hotplug (and therefore resume) to correctly reinitialize MCEs when a AP boots again after being offlined. Just drop the check.
