avfilter/asrc_flite: Fix use-after-frees

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.
