nfsd: export proper maximum file size to the client
I noticed that we export a way to high value for the maxfilesize
attribute when debugging a client issue. The issue didn't turn
out to be related to it, but I think we should export it, so that
clients can limit what write sizes they accept before hitting
the server.
