When doing the very first adapter recovery - initialization - for a FCP device in a point-to-point topology we also allocate the port object corresponding to the attached remote port, and trigger a port recovery for it that will run after the adapter recovery finished. Right now this happens right after we finished with the exchange config data command, and uses the fibre channel host object corresponding to the FCP device to determine whether a point-to-point topology is used. When moving the scsi host object allocation and registration - and thus also the fibre channel host object allocation - to after the first exchange config and exchange port data, this use of the fc_host object is not possible anymore at that point in the work flow. But the allocation and recovery trigger doesn't have notable side-effects on the following exchange port data processing, so we can move those to after xport data, and thus also to after the scsi host object allocation, once we move it. Then the fc_host object can be used again, like it is now. For any further adapter recoveries this doesn't change anything, because at that point the port object already exists and recovery is triggered elsewhere for existing port objects.
