Note that this comment is dangling in your patch:

+{
+       Page            page = BufferGetPage(buffer);
+
+       /* nor when there are no tuples to freeze */
...
-       /* Caller should not call me on a non-WAL-logged relation */
-       Assert(RelationNeedsWAL(reln));
-       /* nor when there are no tuples to freeze */
-       Assert(ntuples > 0);
