USB: hub: fix SS hub-descriptor handling commit 2c25a2c818023df64463aac3288a9f969491e507 upstream. A SuperSpeed hub descriptor does not have any variable-length fields so bail out when reading a short descriptor. This avoids parsing and leaking two bytes of uninitialised slab data through sysfs removable-attributes.
