When an flite filter instance is uninitialized and the refcount of the corresponding voice_entry reaches zero, the voice is unregistered, yet the voice_entry's pointer to the voice is not reset. (Whereas some other pointers are needlessly reset.) Because of this a new flite filter instance will believe said voice to already be registered, leading to use-after-frees. Fix this by resetting the right pointer instead of the wrong ones.
