ca: remove state check in secondarySetPrimaryRoots

This function is only ever called from operations that have already acquired the state lock, so checking
the value of state can never fail.

This change is being made in preparation for splitting out a separate type for the secondary logic. The
state can't easily be shared, so really only the expored top-level functions should acquire the 'state lock'.
