Fix incorrect call to 'bind' in scheduler
I previously submitted https://github.com/kubernetes/kubernetes/pull/49661 -- I'm not sure if that PR is too big or what, but this is an attempt at a smaller PR that makes progress on the same issue and is easier to review.
**What this PR does / why we need it**:
In this refactor (https://github.com/kubernetes/kubernetes/commit/ecb962e6585#diff-67f2b61521299ca8d8687b0933bbfb19R223) the scheduler code was refactored into separate `bind` and `assume` functions. When that happened, `bind` was called with `pod` as an argument. The argument to `bind` should be the assumed pod, not the original pod. Evidence that `assumedPod` is the correct argument bind and not `pod`: 80f26fa8a8/plugin/pkg/scheduler/scheduler.go (L229-L234). (and it says `assumed` in the function signature for `bind`, even though it's not called with the assumed pod as an argument).
This is an issue (and causes #49314, where pods that fail to bind to a node get stuck indefinitely) in the following scenario:
1. The pod fails to bind to the node
2. `bind` calls `ForgetPod` with the `pod` argument
3. since `ForgetPod` is expecting the assumed pod as an argument (because that's what's in the scheduler cache), it fails with an error like `scheduler cache ForgetPod failed: pod test-677550-rc-edit-namespace/nginx-jvn09 state was assumed on a different node`
4. The pod gets lost forever because of some incomplete error handling (which I haven't addressed here in the interest of making a simpler PR)
In this PR I've fixed the call to `bind` and modified the tests to make sure that `ForgetPod` gets called with the correct argument (the assumed pod) when binding fails.
**Which issue this PR fixes**: fixes#49314
