scsi: qla1280: Fix compiler warnings (DEBUG mode)

Building the qla1280 driver with DEBUG_QLA1280 set will emit compiler
warnings. Fix some print formatting strings to reflect the correct type
of printed variables as well as remove unused code. (static function
ql1280_dump_device) in order to avoid compiler warnings.

[mkp: fixed a few more checkpatch warnings]
