[SCSI] zfcp: Simplify handling of ct and els requests
Remove some redundancies in FC related code and trace: - drop redundant data from SAN trace (local s_id that only changes during link down, ls_code that is already part of payload, d_id in ct response trace that is always the same as in ct request trace) - use one common fsf struct to hold zfcp data for ct and els requests - leverage common fsf struct for FC passthrough job data, allocate it with dd_bsg_data for passthrough requests and unify common code for ct and els passthrough request - simplify callback handling in zfcp_fc Reviewed-by: Swen Schillig <swen@vnet.ibm.com> Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
