What's the state of sdev->tagged_queue

[Christoph Hellwig <hch@lst.de>]

Hi Doug,

scsi_ioctl.c has the following comment from you:

 * The next two ioctls either need to go or need to be changed to
 * pass tagged queueing changes through the low level drivers.
 * Simply enabling or disabling tagged queueing without the knowledge
 * of the low level driver is a *BAD* thing.

and scsi.h has this:

 unsigned tagged_queue:1;/* This is going away!!!!  Look at simple_tags
                            instead!!!  Please fix your driver now!! */

but several drivers still look at it although it's never touched
outside scsi_ioctl.c and the individual drivers.  Most drivers uses also
look pretty bogus.  Can we just the ioctls and the field?
