Add several quirks:
Western Digital Enterprise drives have sorry performance (1.5MB/sec versus
8MB/sec) when doing tagged queueing. Disable tagged queueing for them.
Submitted by: Andrew Gallatin <gallatin@cs.duke.edu>
Some Sony CDROM drives don't like it when we probe more than one LUN.
Verified by: Jean-Marc Zucconi <jmz@FreeBSD.ORG>
Some Sony CD-R's don't like multi-LUN probing either.
