This adds break statements after the KVM_REG_PPC_PPR case in
kvmppc_get_one_reg() and kvmppc_set_one_reg(). The error was
introduced in commit d3ecc54390 ("KVM: PPC: Book3S HV: Support POWER6
compatibility mode on POWER7"). That commit also forgot to update
Documentation/virtual/kvm/api.txt with the new one_reg identifier,
so we do that here too.
