zfcp: retain trace level for SCSI and HBA FSF response records

commit 35f040df97fa0e94c7851c054ec71533c88b4b81 upstream.

While retaining the actual filtering according to trace level,
the following commits started to write such filtered records
with a hardcoded record level of 1 instead of the actual record level:
commit 250a1352b95e1db3216e5c5d4f4365bea5122f4a
("[SCSI] zfcp: Redesign of the debug tracing for SCSI records.")
commit a54ca0f62f953898b05549391ac2a8a4dad6482b
("[SCSI] zfcp: Redesign of the debug tracing for HBA records.")

Now we can distinguish written records again for offline level filtering.
