My previous fix to clear padding of short frames used skb->len as the
DMA length, assuming that skb_padto() extended skb->len to include the
padding. That isn't the case; we need to use skb_put_padto() instead.
(This wasn't immediately obvious because software padding isn't
actually needed on the R-Car H2. We could make it conditional on
which chip is being driven, but it's probably not worth the effort.)
