Sean Christopherson a4107b422f KVM: PPC: Book3S PR: Free shared page if mmu initialization fails 
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().

Fixes: 96bc451a15329 ("KVM: PPC: Introduce shared page")
