Set interface address from consol tidy output

While trying to see why this is not working for me (forum https://forum.pfsense.org/index.php?topic=83651.0 ) I have fixed some little things:
1) Get the new-lines right so the output of the restarting looks neat
2) Fix a comparison that had just a single equal sign - it did not break anything real because the subsequent code was just text output to the console. Now that text output does take notice of the correctly-evaluated condition, and $interface is not overwritten.

The issue in the forum post, about the interface IP address config not actually changing, is still the case, at least for me.

IMO these little tidy ups might as well be committed. They make this code better!
