I adjusted the function that detects tape block size so that it is 
capped to MAXPHYS. I also fixed the debug message so that I get the
scsireq_t NetBSD field names correctly displayed and filled:

I now get SCCMD_UNKNOWN / Check Condition. I would have expected it to 
issue a SENSE command afterward, but instaed it does this:
