[SCSI] zfcp: Reduce flood on hba trace
Remove tracing for request with a "qualifier" field set in the response. The protocol status qualifier now contains measurement data for "good" commands, so this check would trace every response by default. The fix is to simply remove the "qual" tracing: The responses with an interesting status are also traced as "ferr" or "perr" and all responses can be traced as "norm" with a higher trace level.
