virtio_blk - Fix capacity calculation, when host sets large disk block size.

* The disk capacity in the virtio configuration space is always specified
  in 512 byte sectors, so info.d_media_blksize should be 512.

* Also check for VIRTIO_BLK_F_GEOMETRY feature before reading the disk
  geometry from configuration space.

* Add some device_printf calls to report the disk size and (if available)
  geometry during bootup.
