NFS: Start PF_INET6 callback listener only if IPv6 support is available
Apparently a lot of people need to disable IPv6 completely on their distributor-built systems, which have CONFIG_IPV6_MODULE enabled at build time. They do this by blacklisting the ipv6.ko module. This causes the creation of the NFSv4 callback service listener to fail if CONFIG_IPV6_MODULE is set, but the module cannot be loaded. Now that the kernel's PF_INET6 RPC listeners are completely separate from PF_INET listeners, we can always start PF_INET. Then the NFS client can try to start a PF_INET6 listener, but it isn't required to be available.
