[SCSI] zfcp: Update FSF error reporting
The SCSI midlayer retries commands based on the remote port state and the command status reported by the driver. Returning DID_TRANSPORT_DISRUPTED is a better approach, use this for reporting FSF errors back to the SCSI midlayer. See http://marc.info/?l=linux-scsi&m=125668044215051&w=2 as reference. There is also no need in special treatment of ABORTED commands, so remove the ZFCP_STATUS_FSFREQ_ABORTED, the commands are then returned with DID_TRANSPORT_DISRUPTED. Also remove the ZFCP_STATUS_FSFREQ_RETRY: It is useless, no retry is happening in the FSF layer and nobody checks the state of this flag.
