SFTP: avoid downloading negative sizes!
It is still not clarified exactly why this happens, but libssh2 sometimes report a negative file size for the remote SFTP file and that deeply confuses libcurl (or crashes it) so this precaution is added to avoid badness. Reported by: Ernest Beinrohr Bug: http://curl.haxx.se/bug/view.cgi?id=3076430
