In some cases, if a VLAN is created on top of a bridge, a config reload
can lead to the bridge being torn down while netifd still considers the
VLAN device to be up.
In that case even a setup retry of an interface on top of the vlan does
not recreate the vlan device, because it is still claimed.
Fix this by releasing all device claims whenever a device goes away.
