Bug#1035094: udev: /dev/serial/by-id/ symlinks not created anymore for USB devices

[Kevin Hilman]

I think it's the same root cause, but I also noticed that the
ID_SERIAL_SHORT attribute has disappeared from `udevadm info` for USB
serial adapters.   ID_USB_SERIAL_SHORT is present, but ID_SERIAL_SHORT
is gone, which has broken some udev rules which use ID_SERIAL_SHORT
for matching.
