virtio-blk: multiqueue batch notify
The batch notification BH needs to know which virtqueues to notify when
multiqueue is enabled. Use a bitmap to track the virtqueues with
pending notifications.
At this point there is only one virtqueue so hard-code virtqueue index
0. A later patch will switch to real virtqueue indices.
