[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.
