Christof Schmitt dcd20e2316 [SCSI] zfcp: Only collect SCSI debug data for matching trace levels
The default trace level is to only trace failed SCSI commands. Thus it
is not necessary to collect trace data for most SCSI commands since it
will be thrown away later. Restructure the SCSI trace infrastructure
to first check the trace level in a inline function and only do the
expensive data collection for matching trace levels.
