[BUGFIX] Unnecessary warning in css_styled_content (division by zero)

If tt_content.image.20.maxW is not set, PHP throws a warning about
division by zero. This is not necessary. After that the variable
$scale is not set. This patch checks if $netW is greater zero and
otherwise the else condition will set $scale to 1.
