Done

• Fixed some incorrect markup that was making the edit form unusable if the machine had a tag.
• Fixed some incorrect logic that prevented link speeds and interface speeds to be updated in the dit interface form.

QA

• Go to http://bolla.internal:5240/MAAS/#/machine/t4kwcq?area=network and try to edit the first interface. When you submit the form you should get an error about tags.
• Try to edit the link and interface speeds on the second interface. The form should submit but the values should not be updated.
• Pull this branch and attempt to do the same things on the same machine. Also try to add and remove tags. Everything should work.
