There's no reason to track the atomic state three times. Unfortunately,
this is currently what we're doing, and even worse is that there is only
one actually correct state pointer: the one in mst_state->base.state.
mgr->state never seems to be used, along with the one in
mst_state->state.

This confused me for over 4 hours until I realized there was no magic
behind these pointers. So, let's save everyone else from the trouble.
