[PATCH] tests: silence clang warning

[Eric Blake]

* tests/test-malloca.c (do_allocation): Avoid dead store.

I ran clang on m4, and found a couple of warnings.  It warned
about this as a dead store, and it's easy enough to avoid.

Clang also warned about some potential null dereferences in
gl_avltree_oset.c; but I think it was missing on some additional
constraints (namely, the incoming height_diff must be exactly
-1 or 1, and each node->balance must be in the range [-1..1];
and that the balance also has some implications as to whether
the left or right child must exist), so I'm chalking those
up as spurious warnings (but I don't know how to silence
clang other than to slow down the code by adding cruft like:
if (unlikely(!node->right)) abort();
