Logical resources start with allocation-state:UNUSABLE / isolation-state:ISOLATED. During hotplug, guests will transition them to allocation-state:USABLE, and then to isolation-state:UNISOLATED. For cases where we cannot transition to allocation-state:USABLE, in this case due to no device/resource being association with the logical DRC, we should return an error -3. For physical DRCs, we default to allocation-state:USABLE and stay there, so in this case we should report an error -3 when the guest attempts to make the isolation-state:ISOLATED transition for a DRC with no device associated. These are as documented in PAPR 2.7, 13.5.3.4. We also ensure allocation-state:USABLE when the guest attempts transition to isolation-state:UNISOLATED to deal with misbehaving guests attempting to bring online an unallocated logical resource. This is as documented in PAPR 2.7, 13.7. Currently we implement no such error logic. Fix this by handling these error cases as PAPR defines.
