Windows: fd_to_winfd() shouldn't treat fd 0 as invalid
* fd_to_winfd() currently returns INVALID_WINFD if fd is 0, but usbi_create_fd()
can legally assign an fd number of 0 if poll_fd[0] is not already occupied.
* Transfers which are assigned an fd number of 0 for their event handle are then
unable to have their event handle retrieved later on.
