After that, commit a3172b7eb4a2 ("Bluetooth: Add timer to force power off") introduced a timeout to ensure that the device actually got powered off, even if some of the cleanup work would never complete. This code later got refactored with commit cf75ad8b41d2 ("Bluetooth: hci_sync: Convert MGMT_SET_POWERED"), which made powering off the device synchronous and removed the need for initiating the power_off work from other places. The timeout mentioned above got removed too, because we now also made use of the command timeout during power on/off. These days the power_off work still exists, but it only seems to only be used for HCI_AUTO_OFF functionality, which is why we never noticed those two leftover places where we queue power_off work. So let's remove that code.
