Kirill Kapranov 687ca6395f USB: adutux: Add waiting in transfer abortion
Add waiting for an URB transmit finish that let the last URB to be sent
(to be not discarded) during 'release' procedure. W/o this waiting,the
last frame will be nearly always lost.

A test case: an attempt of sending a single frame:
echo -en "\001mk255" >/dev/adutux0
