[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.
