Stefan Hajnoczi baf422684d virtio-blk: use BDRV_REQ_REGISTERED_BUF optimization hint 
Register guest RAM using BlockRAMRegistrar and set the
BDRV_REQ_REGISTERED_BUF flag so block drivers can optimize memory
accesses in I/O requests.

This is for vdpa-blk, vhost-user-blk, and other I/O interfaces that rely
on DMA mapping/unmapping.
