I actually plan to remove CONFIG_BLK_SCSI_REQUEST in a merge window
or two.  The only users are scsi and the ide layer, (virtio_blk
support has already been accidentally disabled for a while), and getting
rid of it allows to to shrink and simply the scsi data structures.

But if you want this for now lets keep scsi_sense.c in drivers/scsi
but depend on CONFIG_BLK_SCSI_REQUEST, that is easy enough to fix up.
