From: Shyam Prasad N <sprasad@xxxxxxxxxxxxx> commit 05ce0448c3f36febd8db0ee0e9e16557f3ab5ee8 upstream. Before my changes to how multichannel reconnects work, the primary channel was always used to do a non-binding session setup. With my changes, that is not the case anymore. Missed this place where channel at index 0 was forcibly updated with the signing key.
