[kernel PATCH v1 0/1] Clear workqueue to avoid use-after-free

[Zhengping Jiang]

After the hci_sync rework, cmd_sync_work was cleared when calling
hci_unregister_dev, but not when powering off the adapter.
Use-after-free errors happened because a work is still scheduled
when cmd is freed by __mgmt_power_off.

Changes in v1:
- Clear cmd_sync_work queue before clearing the mgmt cmd list
