thor: fix invalid larger device descriptor than requested

New Linux kernel xhci hub uses new usb descriptor scheme first for
high speed usb peripheral device and it requests 8 bytes usb device
descriptor and then 18 bytes full usb device descriptor but thor
cdc-acm gadget always sends 18 bytes full usb device descriptor,
so thor download mode is failed to recognize for linux host with
new scheme. Fix the invalid larger device descriptor than
requested by sending only requested bytes.
