Windows: Allow synchronous control transfers (for libusb0)
Some of the changes in commit 9c28ad2 rely on all transfers having (or
appearing to have) asynchronous completion.
However, the libusb0.sys backend of libusbk.dll performs all control
transfers synchronously and ignores any "overlapped" structure handed to
it. Our asynchronous handling will in this case be pending and
eventually time out although the USB request itself was successful.
Therefore restore the possibility of synchronous completion of control
transfers, by forcing the completion handling on a successful return
from request submission. This brings the code closer to how it was
established in commit ce95f65.
