tools: fix atomic_set() definition to set the value correctly

Currently vma test is failing because of the new vma_assert_attached()
assertion.  The check is failing because previous refcount_set() inside
vma_mark_attached() is a NoOp.  Fix the definition of atomic_set() to
correctly set the value of the atomic.
