KVM: PPC: Book3S PR: return appropriate error when allocation fails
err was overwritten by a previous function call, and checked to be 0. If the following page allocation fails, 0 is going to be returned instead of -ENOMEM. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
