Without thinking about the implications for a fix, I don't think that it makes sense if an `iolist` element calls any tx_load or whatever SPI triggering function if `len` is zero. However, IMO it's reasonable to check `len` under the user API so (3) would be the most sensible solution here from my perspective.
