KVM: x86: Fix probable memory leak of vcpu->arch.mce_banks

vcpu->arch.mce_banks is malloc in kvm_arch_vcpu_init(), but never free in any place, this may cause memory leak. So this patch fixed to free it in kvm_arch_vcpu_uninit(). Cc: [email protected] Signed-off-by: Wei Yongjun <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
