fib: support "midchain delegate" removal
Type: improvement Currently, once an adjacency is stacked on a FIB entry via adj_midchain_delegate_stack(), "midchain delegate" is created for the adjacency and the FIB index is stored there. And all further calls to adj_midchain_delegate_stack() even passing another FIB index will cause the function to still use the stored one. In other words, there is currently no way to stack an adjacency on another FIB index if "midchain delegate" already exists for it. Being able to stack on another FIB index is needed for the wireguard plugin. As per the protocol, peers can roam between different external endpoints. When an authenticated packet is received and it was sent from a different endpoint than currently stored, the endpoint needs to be updated and all futher communication needs to happen with that endpoint. Thus, the corresponding to that peer adjacencies need to be stacked on the FIB entry that corresponds to the new endpoint. With this change, add adj_midchain_delegate_remove() that removes "midchain delegate". When stacking on another FIB entry is needed, existing "midchain delegate" can be removed and then, a new one created with a new FIB index via adj_midchain_delegate_stack().
