pppoe: drop pppoe device in pppoe_unbind_sock_work

After receiving a PADT and the socket is closed, user space will no
longer drop the reference to the pppoe device.
This leads to errors like this:

[  488.570000] unregister_netdevice: waiting for eth0.2 to become free. Usage count = 2

Fixes: 287f3a943fe ("pppoe: Use workqueue to die properly when a PADT is received")
