    ofpathname: speed up l2of_scsi()
    
    There is no need to search the entire /sys hierarchy for kernel device
    names like "sda". We know that if it is present it will be in
    /sys/class/block.
    
    In an environment with more than 800 scsi devices, this brings the
    execution time for a command like "lsdevinfo -F name -c -q
    parent=host1" from over 20 minutes to under two minutes.
