CVE-2022-49127

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

ref_tracker: implement use-after-free detection

Whenever ref_tracker_dir_init() is called, mark the struct ref_tracker_dir as dead.

Test the dead status from ref_tracker_alloc() and ref_tracker_free()

This should detect buggy dev_put()/dev_hold() happening too late in netdevice dismantle process.
