When establishing and activating the QDIO queue pair for a FCP device for the first time, or after an adapter recovery, we publish some of its characteristics to the scsi host object representing that FCP device. When moving the scsi host object allocation and registration to after the first exchange config and exchange port data, this is not possible for the former case - QDIO open for the first time - because that happens before exchange config and exchange port data. Move the scsi host object update into a fenced function that checks whether the object already exists or not. This way we can repeat that step later, once we are past the allocation. Once the first recovery succeeds we don't release the scsi host object anymore, so further recoveries do work as before.
