SUNRPC: Use "sockaddr_storage" for storing RPC client's remote peer address
IPv6 addresses are big (128 bytes). Now that no RPC client consumers treat
the addr field in rpc_xprt structs as an opaque, and access it only via the
API calls, we can safely widen the field in the rpc_xprt struct to
accomodate larger addresses.
Test plan:
Compile kernel with CONFIG_NFS enabled.
