The driver does not compile under DEBUG_QLA1280 flag:
- Debug statements expect an integer for printing a SCSI lun value, but
  its size is 64b. So change SCSI_LUN_32() to cast to an int, as would be
  expected from a "_32" function.
- lower_32_bits() expects %x, as opposed to %lx, so fix that.

Also delete ql1280_dump_device(), which looks to have never been
referenced.

How about using 'unsigned int' instead of 'int' since LUN numbers are 
positive integers?

Thanks,

Bart.

All the use points in the driver are ints currently so matching the use
makes more sense than matching the standard and risking signed to
unsigned conversion warnings.
