hook git clone failures

[BenTheElder]

What happened:

jsonPayload: {
  client: "git"   
  component: "hook"   
  file: "prow/git/git.go:389"   
  func: "k8s.io/test-infra/prow/git.retryCmd"   
  level: "warning"   
  msg: "Running /usr/bin/git [clone --mirror https://k8s-ci-robot:CENSORED@github.com/kubernetes/kubernetes /tmp/git880570593/kubernetes/kubernetes.git] returned error exit status 128 with output Cloning into bare repository '/tmp/git880570593/kubernetes/kubernetes.git'...
fatal: remote error: upload-pack: not our ref 6435c6df2a382b4e8278af486fb646e84089af80

."   
 }

What you expected to happen: cloning to work

How to reproduce it (as minimally and precisely as possible): unclear. this is happening in the prow.k8s.io deployment

Please provide links to example occurrences, if any: visible in the cluster logs if you have access

Anything else we need to know?: this is happening repeatedly.

looks like these are probably for unmerged commits. possibly just pushed
