Subject: bond: bridge: T4534: error out if member interface is assigned to a
 VRF instance

It makes no sense to enslave an interface to a bond or a bridge device if it is
bound to a given VRF. If VRFs should be used - the encapuslating/master
interface should be part of the VRF.

Error out if the member interface is part of a VRF.

(cherry picked from commit 87d2dff241d9ab4de9f3a2c7fbf9852934557aef)
