block/vdi: Add locking for parallel requests
When allocating a new cluster, the first write to it must be the one doing the allocation, because that one pads its write request to the cluster size; if another write to that cluster is executed before it, that write will be overwritten due to the padding. See https://bugs.launchpad.net/qemu/+bug/1422307 for what can go wrong without this patch.
