[PATCH] knfsd: SUNRPC: Add a function to format the address in an svc_rqst for printing
There are loads of places where the RPC server assumes that the rq_addr fields contains an IPv4 address. Top among these are error and debugging messages that display the server's IP address. Let's refactor the address printing into a separate function that's smart enough to figure out the difference between IPv4 and IPv6 addresses.
