NFS: pnfs IPv6 support
Handle ipv6 remote addresses from GETDEVICEINFO
- supports netid "tcp" for ipv4 and "tcp6" for ipv6 as rfc 5665 specifies
- added ds_remotestr to avoid having to handle different AFs in every dprintk
- tested against pynfs 4.1 server, submitting ipv6 support patch to pynfs
- tested with IPv6 disabled, it compiles cleanly and relies on rpc_pton to
refuse to accept IPv6 addresses
