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.
