Andi Kleen cf9b303e55 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.
