Dan Carpenter 5c1f50ab7f KVM: Fix a goof where kvm_create_vm() returns 0 instead of -ENOMEM ... The error path for OOM when allocating buses used to return -ENOMEM using the local variable 'r', where 'r' was initialized at the top of the function. But a new "r = kvm_init_irq_routing(kvm);" was introduced in the middle of the function, so now the error code is not set and it eventually leads to a NULL dereference due to kvm_dev_ioctl_create_vm() thinking kvm_create_vm() succeeded. Set the error code back to -ENOMEM. Opportunistically tweak the logic to pre-set "r = -ENOMEM" immediately before the flows that can fail due to memory allocation failure to make it less likely that the bug recurs in the future.
