zfcp: trace full payload of all SAN records (req,resp,iels)

Browse source

commit aceeffbb59 upstream.

This was lost with commit 2c55b750a8
("[SCSI] zfcp: Redesign of the debug tracing for SAN records.")
but is necessary for problem determination, e.g. to see the
currently active zone set during automatic port scan.

For the large GPN_FT response (4 pages), save space by not dumping
any empty residual entries.
