virtio_blk: fix incorrect message when disk is resized
The message printed on disk resize is incorrect. The following is
printed when resizing to 2 GiB:
$ truncate -s 1G test.img
$ qemu -device virtio-blk-pci,logical_block_size=4096,...
(qemu) block_resize drive1 2G
virtio_blk virtio0: new size: 4194304 4096-byte logical blocks (17.2 GB/16.0 GiB)
The virtio_blk capacity config field is in 512-byte sector units
regardless of logical_block_size as per the VIRTIO specification.
Therefore the message should read:
virtio_blk virtio0: new size: 524288 4096-byte logical blocks (2.15 GB/2.0 GiB)
Note that this only affects the printed message. Thankfully the actual
block device has the correct size because the block layer expects
capacity in sectors.
