Set initial baudrate on correct interface instead of always the first one (Thimo Eichstaedt)

From libftdi mailinglist mail:
1) in ftdi_usb_open_dev() the baudrate is set to 9600, but that is done
too early (before the interface is set). So the baudrate of the first
interface is always modified, even if you opened a different one.
