windows: Fix iSerial for composite devices.

USB composite devices can contain an ACM serial interface.
On Windows, the correct iSerial descriptor field is assigned to the parent
(composite) device instead of to the actual serial interface. A bogus
value is returned if the serial interface is asked to provide the S/N.
This patch provides a fallback for this kind of device (tested on Android
with adb + cdc gadgets and on Arduino Zero Programming Port)
