Hm, while it very unlikely, it seems that we currently access that
counter variable non-atomic. This may, in theory, result in two
identical reqids if two threads create CHILD_SAs simultaneously.

Hard to say if this is actually the issue that lead to these non-unqiue
reqids. Anyway, we should fix that, and I've done so with the three
patches at [1].
