Tom Rini 2fc62f2991 stackprot: Make our test a bit more complex ...

With better compiler optimizations available, a compiler may see we do
nothing with our buffer after calling memset and omit the call, thus
causing us to not smash the stack.  Add a comment to explain why we now
also have a printf call, so that the test will pass as the memset will
not be omitted.
