lfs: default to not using workers for upload/download

I ran into truncated uploads with this defaulting to on.  Wojciech Lis diagnosed
it as creating keepalive connections prior to forking, and illegally
multiplexing the same connection. [1]  I didn't notice a problem with the couple
of downloads I tried, but disabled both for simplicity and safety.
