Allocation API has GPU costs when GPU count is 0

[keithhand]

Describe the bug
When using a custom pricing model, GPU prices can be assigned to __idle__ costs, even though the GPU count for the node is 0.

To Reproduce
Steps to reproduce the behavior:

1. Create a cluster with no GPU-enabled nodes.
2. Install Kubecost with kubecostProductConfigs.customPricesEnabled = true in the values.yaml. The default pricing values will work to demonstrate the bug.
3. Navigate to the Cost Allocation page and see __idle__ GPU costs.

Expected behavior
GPU costs should be $0.

I wanted to note that a quick workaround here is to set GPU prices to 0 in your default pricing settings.

I will do a bit of digging to see if I can help narrow down the cause, but assigning to @dramich since it's a good chance to dive into a messy bit of the code base :)

@dramich any update here?
