Add new helper to disable connections to interfaces that have already been disconnected (e.g. forcibly removed). The connection tear-down procedure differs enough depending on whether the interface is still present or already gone to warrant a dedicated helper. This will become more obvious with the new tear-down procedure, which involves I/O on the connection being tore down. This also simplifies handling of the legacy bootrom, which does not support the new tear-down operations. Specifically, this allows us to remove the early control-connection tear down during interface disable, and also avoids some error messages currently printed during legacy mode switch (i.e. bootrom boot-over-UniPro) and forcible removal.
