[OpenMP][FIX] Avoid a race between initialization and first state reads When we pick state 0 to initialize state but thread N is going to be the "main thread", in generic mode, we would require extra synchronization. Instead, we should pick the main thread to initialize state in generic mode and any thread in SPMD mode.
