cli/command/volumes: minor cleanups: use Println, rename vars

- use Println to print newline instead of custom format
- use apiClient instead of client for the API client to
  prevent shadowing imports.
- use dockerCLI with Go's standard camelCase casing.
- suppress some errors to make my IDE and linters happier
