nbd/server: Prefer heap over stack for parsing client names
As long as we limit NBD names to 256 bytes (the bare minimum permitted by the standard), stack-allocation works for parsing a name received from the client. But as mentioned in a comment, we eventually want to permit up to the 4k maximum of the NBD standard, which is too large for stack allocation; so switch everything in the server to use heap allocation. For now, there is no change in actually supported name length.
