Stack trace after resume

On an ASUS ROG Ally X (and possibly Legion Go) and a kernel of 6.11+, if
Bluetooth is enabled, hibernation will fail on resume with RIP
__list_del_entry_valid_or_report.cold.

This is under the function hci_unregister_dev

6.10 appears to work however. See the stack trace below. It is from a tainted
6.11 kernel, but the same issue occurs on 6.12.0 and 6.11.y

Bisection between 6.10 and 6.11 made some kernels that could not boot, so I
could not finish it. I also tried reverting "Fix not handling hibernation
actions" and "Bluetooth: btusb: Don't fail external suspend requests"
completely which did not help

The following lines were used to produce the trace:
```
sudo chvt 2
echo N | sudo tee /sys/module/printk/parameters/console_suspend
echo devices | sudo tee /sys/power/pm_test
echo disk | sudo tee /sys/power/state
```
