Unable to create split role cluster

[dereknola]

Environmental Info:
K3s Version:

v1.29.2-rc1+k3s1

Cluster Configuration:

3 Etcd only nodes
2 Control Plane nodes
1 Agent

Describe the bug:

Tracked back to #9184. This has changes the order of when the AgentReady channel is closed. This results in a endless loop, as kubelet waits for etcd to start, and etcd waits for the channel to be closed.

Steps To Reproduce:

• Installed K3s: Any of the Feburary 2024 RCs
• Configure a cluster with at least 3 etcd-only nodes

Expected behavior:

All cluster nodes come up.

Actual behavior:

The 1st etcd nodes comes up partially, and the other 2 etcd nodes are stuck in an endless initialization loop.

Closing as this was found via KDM CI and is now passing there.
