Update specs to the actual expected values.

[NAR]

The code in finalize_and_stop actually expects {save_state, State} or {ok, State}, so let's specify that in the specs.

Thanks!

But hm, I don't see this function actually used anywhere.. maybe its an artifact from past versions

The deactivate is called from

erleans/src/erleans_grain.erl

Line 430 in 6bb6e3d

case erleans_utils:fun_or_default(CbModule, deactivate, 1, [CbData], {ok, CbData}) of

finalize_and_stop is called from terminate at

erleans/src/erleans_grain.erl

Line 386 in 6bb6e3d

_ = finalize_and_stop(Data),

terminate is called when the grain stops.

Oh, derp! Thanks, shows how long it has been since I've looked used this code :(
