CHROMIUM: drivers: ar8216: hold ar8xxx_dev_list_lock during use_count--
It is possible for the remove() callback to run twice in parallel, which
could result into --use_count returning only 1 in both cases and the
rest of the unregistration path to never be reached.
This case has never been observed in practice, but we will fix
preventively to make the code more robust.
