Summary
Bluetooth: hci_core: cancel all works upon hci_unregister_dev()
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hcicore: cancel all works upon hciunregister_dev()

syzbot is reporting that calling hcireleasedev() from hcierrorreset() due to hcidevput() from hcierrorreset() can cause deadlock at destroyworkqueue(), for hcierrorreset() is called from hdev->reqworkqueue which destroy_workqueue() needs to flush.

We need to make sure that hdev->{rxwork,cmdwork,txwork} which are queued into hdev->workqueue and hdev->{poweron,errorreset} which are queued into hdev->reqworkqueue are no longer running by the moment

   destroy_workqueue(hdev->workqueue);
   destroy_workqueue(hdev->req_workqueue);

are called from hcireleasedev().

Call cancelworksync() on these work items from hciunregisterdev() as soon as hdev->list is removed from hcidevlist.
