Avoid panic in Cloud CIDR Allocator

**What this PR does / why we need it**:
I suspect a race exists where we attempt to look up the CIDR for a terminating node. By the time `updateCIDRAllocation` is called the node has disappeared. We determine it does not have a cloud CIDR (i.e. Alias IP Range) and attempt to record a `CIDRNotAvailable` node status. Unfortunately we reference `node.Name` while `node` is still nil.

By getting the node before looking up the cloud CIDR we avoid the nil pointer dereference, and potentially fail fast in the case the node has disappeared.

**Which issue(s) this PR fixes**:
Fixes #58181

**Release note**:

```release-note
Avoid panic when failing to allocate a Cloud CIDR (aka GCE Alias IP Range).

Kubernetes

Submit Queue Widget GoDoc Widget CII Best Practices


Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.

Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.

Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.


To start using Kubernetes

See our documentation on kubernetes.io.

Try our interactive tutorial.

Take a free course on Scalable Microservices with Kubernetes.

To start developing Kubernetes

The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.

If you want to build Kubernetes right away there are two options:

You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release

For the full story, head over to the developer's documentation.

Support

If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.

That said, if you have questions, reach out to us one way or another.
