Again so we dont forget to fix this

So we dont forget to actually fix the lack of error handling

These are from inl going back to 32bit

Som boards dont seem to be in spec

	RIP.  It's not used anymore, so we kill assignments to it and the
field itself.  That was the last serious use of kdev_t in block drivers.

	* in floppy drivers and ps2esdi - replaced with use of ->rq_disk;
floppy drivers already have information about "type" part of device number
- they had stored that information in floppy_open(), so all we need is a
"which drive" part.  And that is available from ->rq_disk.
	* DAC960: changed ->private_data initialization - instead of pointing
it to controller (which we already have as disk->queue.queuedata) we simply
store a disk number in there.  That had simplified ->revalidate_disk() and
allowed to kill the use of ->rq_dev in request handler.

	* killed the uses of ->rq_dev in printks - several drivers.

	* uses in ll_rw_blk.c and elevator.c eliminated - ->rq_disk has
everything we need.

	* eliminated, since we actually wanted the name, not device number
(BTW, that had also killed calculation of name that used to duplicate sd.c
one)

	_Now_ we can clean the scsi_get_request_dev() up.  Indeed, for
any SCSI request we either have ->rq_dev == NODEV and ->rq_disk == NULL
or ->rq_disk->private_data points to address of template in question.
IOW, scsi_get_request_dev() becomes simply
{
	struct gendisk *p = req->rq_disk;
	return p ? *(struct Scsi_Device_Template **)p->private_data : NULL;
}
and that allows to kill ->max_major, ->min_major and ->major in
Scsi_Device_Template, along with the last non-trivial use of ->rq_dev.

	Ditto for sg.c

	Ditto for sd.c
