fix: Update DEFAULT_BRANCH and VALIDATE_ALL_CODEBASE in lint workflow

The commit fixes the lint workflow by updating the DEFAULT_BRANCH to use github.ref_name and setting VALIDATE_ALL_CODEBASE based on github.event_name for non-pull_request events. Also, minor formatting adjustment in kvm_generic.sh.
