Well, max_sectors is already bounded by this.  max_hw_sectors only
really matters for PC commands, so I'm not sure it's a big deal for
DM. But I guess we could set the default max_hw_sectors to -1.

I'm just trying to avoid these scattered if-0-set-it-to-something-else
cases.  I'd much rather have the defaults do the right thing.
