Subject: [ 015/120] lguest: fix occasional crash in example launcher.

3.4-stable review patch.  If anyone has any objections, please let me know.

From: Rusty Russell <rusty@...tcorp.com.au>

commit ca16f580a5db7e60bfafe59a50bb133bd3347491 upstream.

We usually got away with ->next on the final entry being NULL, but it
finally bit me.
