[Libreoffice] va_start without va_end

[Julien Nabet]

Hello,

In svl/source/items/itemset.cxx b/svl/source/items/itemset.cxx, I 
noticed the use of va_start without va_end.
I read it could create undefined behaviour, so I propose this simple patch.

I propose this patch :
diff --git a/svl/source/items/itemset.cxx b/svl/source/items/itemset.cxx
index 3be762d..0ca7223 100644
--- a/svl/source/items/itemset.cxx
+++ b/svl/source/items/itemset.cxx
@@ -225,6 +225,7 @@ SfxItemSet::SfxItemSet( SfxItemPool& rPool,
              pArgs, sal::static_int_cast< sal_uInt16 >(nWh1),
              sal::static_int_cast< sal_uInt16 >(nWh2),
              sal::static_int_cast< sal_uInt16 >(nNull));
+        va_end(pArgs);
      }
  }

If it's ok, i can commit and push it on master.

Julien.
