If the RX link pointer is NULL, RX DMA has been halted. This means
the first buffer re-added to the list should be given to the hardware.

This doesn't restart DMA by itself; I'l follow up with some tinkering
to try and re-enable it without having to forcibly stop and restart
the PCU.

Whilst here, add a comment to point out another thing I need to tinker
with.
