When the ax25 device is detaching, deallocate the dev_tracker of ax25_cb in ax25_kill_by_device() instead of deallocating the dev_tracker of ax25_dev.
ax25 dev_tracker deallocation target during device detach = ax25_cb (instead of ax25_dev) - Configuration
In ax25_bind(), set/associate ax25_dev's dev_tracker to the dev_tracker of ax25_cb (i.e., 'Change ax25_dev->dev_tracker to the dev_tracker of ax25_cb').
ax25 dev_tracker association during bind = dev_tracker from ax25_cb
