NFSv2/v3: Remove incorrect dprintks from the readdir reply code

The actual size of the directory is unknown to the client, so it is
always requesting the maximum number it can handle. If the server
is replying with fewer entries than was requested, then that will
usually reflect the fact that we've hit the end of the directory.
Flagging it as an error is therefore incorrect.
