Removing duplicate !options case

I haven't actually tested this code, but was reading it due to a post that linked to the code here: http://dailyjs.com/2013/09/26/libuv/

As I was reading through the code, I noticed a code path that can't be reached.

I didn't strictly follow the contributing guide: https://github.com/joyent/node/wiki/Contributing, but the change seems safe.

Feel free to close this out. I'm not sure if it was just an oversight or what.  The github diff doesn't make the change clear, but the very first if() statement in each case contains:  "|| !options".  I'm just removing the "if else (!options)" case.
