NFS: Revert creation of IPv6 listeners for lockd and NFSv4 callbacks

We're about to convert over to using separate PF_INET and PF_INET6 listeners, instead of a single PF_INET6 listener that also receives AF_INET requests and maps them to AF_INET6. Clear the way by removing the logic in lockd and the NFSv4 callback server that creates an AF_INET6 service listener.
