block-backend: remove blk_flush_all
We can teach Xen to drain and flush each device as it needs to, instead of trying to flush ALL devices. This removes the last user of blk_flush_all. The function is therefore removed under the premise that any new uses of blk_flush_all would be the wrong paradigm: either flush the single device that requires flushing, or use an appropriate flush_all mechanism from outside of the BlkBackend layer.
