firewire: ohci: handle receive packets with a data length of zero
commit 8c0c0cc2d9f4c523fde04bdfe41e4380dec8ee54 upstream.
Queueing to receive an ISO packet with a payload length of zero
silently does nothing in dualbuffer mode, and crashes the kernel in
packet-per-buffer mode. Return an error in dualbuffer mode, because
the DMA controller won't let us do what we want, and work correctly in
packet-per-buffer mode.
