Fix non-lazy ternery expression

The ansible 'ternery' filter is not a real (lazy) ternery operator meaning that
both branches are evaluated regardless of the input. Prior to this patch, this
would erroneously result in a crash if 'interface' was not specified.

Also includes unrelated linter-requested whitespace changes.
