[PATCH 3/6] Remove attached adjacencies whenever an interface is disabled for whatever reason.

[Renato Westphal]

If one interface is disabled, the holdtimer of the attached adjacencies
will eventually timeout after a few seconds. But there's no need to wait
when we know that the interface is disabled. In these cases, remove the
attached adjacencies to speedup the convergence process.
