This patch fixes the problem reported by Sergei:
how come? we need to send ZLP before giving back the request.
Well, look at the code ionce again. We need to send ZLP *after*
request->actual == request->length, but as the check is inserted
after the ZLP send, ZLP *may* be sent once the first DMA completes,
not the last.
The patch also has been discussed on the link below:
