The current limit of 32 bytes artificially limits the name string that we end up stuffing into NFSv4.x client ID blobs. If you have multiple hosts with long hostnames that only differ near the end, then this can cause NFSv4 client ID collisions. Linux nodenames are actually limited to __NEW_UTS_LEN bytes (64), so use that as the limit instead. Also, use XDR_QUADLEN to specify the slack length, just for clarity and in case someone in the future changes this to something not evenly divisible by 4.
