If a device morphs we will get uas_disconnect() called before the kernel re-enumerates the device, so then we will still have all the old endpoints in the interface struct, and freeing the streams should work fine. Note that freeing the streams is an controller level operation, nothing is send to the device, and since at this point all our state still reflects the old descriptors of the device everything should be fine.
