4be8c22e74 generic: ar8216: add detach callback
The current code uses the 'remove' callback to disable
packet mangle on the underlying ethernet device.
However the attached_dev is always NULL when the
'remove' callback is called by phylib, and this causes
NULL pointer dereference, like this:

98f30aac8e generic: ar8216: rename AR8216_*_STATS_* defines

Thanks to Jonas Gorski for the report.
