Test trim of last small AG for large filesystem resizes
As reported at
http://article.gmane.org/gmane.comp.file-systems.xfs.general/29187
this trimming may cause an overflow in the new size calculation.
Patch to fix it, and testcase at
http://article.gmane.org/gmane.comp.file-systems.xfs.general/29193
V2: now with proper expected (resized) output!
