[SCSI] sd: disentangle barriers in SCSI
Our current implementation has a generic set of barrier functions that
go through the SCSI driver model. Realistically, this is unnecessary,
because the only device that can use barriers (sd) can set the flush
functions up at probe or revalidate time. This patch pulls the barrier
functions out of the mid layer and scsi driver model and relocates them
directly in sd.
