Subject: [PATCH] prow.sh: fix "on-master" prow jobs

The recent introduction of version_to_git broke Prow jobs with
CSI_PROW_KUBERNETES_VERSION=latest because that version was first
converted to "master" and then once more to "vmaster". The second call
must be idempotent because "master" is already a branch name.
