nfsd: don't abort copies early
commit bfdd89f2 upstream. The typical result of the backwards comparison here is that the source server in a server-to-server copy will return BAD_STATEID within a few seconds of the copy starting, instead of giving the copy a full lease period, so the copy_file_range() call will end up unnecessarily returning a short read.
