KVM: x86: Fix leak of free lapic date in kvm_arch_vcpu_init()
In function kvm_arch_vcpu_init(), if the memory malloc for vcpu->arch.mce_banks is fail, it does not free the memory of lapic date. This patch fixed it. Cc: stable@kernel.org Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
