From: Sean Christopherson <sean.j.christopherson@intel.com> commit cb10bf9194f4d2c5d830eddca861f7ca0fecdbb4 upstream. Explicitly free the shared page if kvmppc_mmu_init() fails during kvmppc_core_vcpu_create(), as the page is freed only in kvmppc_core_vcpu_free(), which is not reached via kvm_vcpu_uninit().
