[SCSI] advansys: Comment/indentation/macro cleanup
- Delete comments relating to the previous structure of the driver.
I have no intention of honouring them ;-)
- Reformat comments > 80 columns
- Remove now-obsolete comments from advansys_interrupt
- Change adv_get_sglist() from do {} while (1) to for (;;)
- Return void from AscInitQLinkVar()
- Take out a level of indentation in adv_get_sglist()
- Reduce indentation level of AscAsyncFix()
- Remove unused macros
- Refactor AscSendScsiQueue slightly
