[CrOS Network] Fix layout UI issue on "known networks" settings page.

A refactor [1] introduced use of the <cr-link-row> element, but some of
the contents which were supposed to be within the element itself were
erroneously placed after the </cr-link-row> tag instead.

This CL moves the contents to the correct place and also removes a stray
</div> tag which should not have been there.
