Pawan Gupta f29dfa53cc x86/bugs/multihit: Fix mitigation reporting when VMX is not in use 
On systems that have virtualization disabled or unsupported, sysfs
mitigation for X86_BUG_ITLB_MULTIHIT is reported incorrectly as:

  $ cat /sys/devices/system/cpu/vulnerabilities/itlb_multihit
  KVM: Vulnerable

System is not vulnerable to DoS attack from a rogue guest when
virtualization is disabled or unsupported in the hardware. Change the
mitigation reporting for these cases.

Fixes: b8e8c8303f ("kvm: mmu: ITLB_MULTIHIT mitigation")
