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: stable@kernel.org Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
