KVM: Explicity initialize cpus_hardware_enabled
commit a4c0364be3f43d3e17fe19270f8b3d64881606e6 upstream.
Under CONFIG_MAXSMP, cpus_hardware_enabled is allocated from the heap and
not statically initialized. This causes a crash on reboot when kvm thinks
vmx is enabled on random nonexistent cpus and accesses nonexistent percpu
lists.
Fix by explicitly clearing the variable.
