[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
