Tobias Herzog 1bb9914e17 cdc-acm: fix possible invalid access when processing notification
Notifications may only be 8 bytes long. Accessing the 9th and
10th byte of unimplemented/unknown notifications may be insecure.
Also check the length of known notifications before accessing anything
behind the 8th byte.
