Bluetooth: btusb: fix use-after-free on registration failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: fix use-after-free on registration failure
Make sure to release the sibling interfaces in case controller
registration fails to avoid use-after-free and double-free when they are
eventually disconnected.
This issue was reported by Sashiko while reviewing a fix for a wakeup
source leak in the btusb probe errors paths.
