This will allow us to resize the backend bdev of vhost-blk
and notify the guest OS that the capactiy of virtio-blk
disk has been resized.
The spdk api entry is `spdk_bdev_notify_blockcnt_change`.
Any bdev if used as vhost-blk backend may need to implement
a rpc that calls this function.
Related DPDK patch has been merged and release in 20.02.
