DM: xHCI: Fix the USB3.2 device recognition problem.

Browse Source 
The device descriptor describes general information about a device,
the bcdUSB field contains a BCD version number. The version 3.2 is
represented with value of 0x320H. Add the missed BCD version in the
bcdUSB case statement. And modify the return value of address device
command in case create device failed.
