freedreno/a6xx: WFI in program stateobj too

This "fixes" hangs seen w/ various android games.  I think a similar
issue to with constant state, we need to avoid CP_LOAD_STATE until
previous draw completes.

It isn't entirely clear why blob doesn't need to do this, but it might
have a different way to accomplish the same thing.
