nfsd: let nfsd_symlink assume null-terminated data
Currently nfsd_symlink has a weird hack to serve callers who don't
null-terminate symlink data: it looks ahead at the next byte to see if
it's zero, and copies it to a new buffer to null-terminate if not.
That means callers don't have to null-terminate, but they *do* have to
ensure that the byte following the end of the data is theirs to read.
That's a bit subtle, and the NFSv4 code actually got this wrong.
So let's just throw out that code and let callers pass null-terminated
strings; we've already fixed them to do that.
