SaveState: Show a warning if saved after savestate.

If you load a save state from before you created savedata (or from a
different path of savedata), some games will refuse to save.  This shows a
warning since it can be a confusing situation.

We could potentially add an undo for loading state, to give an option for
getting back after this warning.
