- Exhumed: Optimise UnlinkIgnitedAnim() from fb97e3c6ca a bit.

* Bad cherry pick caused a stat iteration over the wrong stat number.
* Cleaned up commentary to reflect that we have actors and not so much sprites or an anim array anymore.

-    Without this, the anim will hold reference to a sprite which will eventually be reused, but the anim code
-    will continue to manipulate its hitag value. This can break runlist records for things like LavaDude
-    limbs that store these in the sprite hitag.
+    Without this, the actor will hold reference to an actor which will prevent the GC from deleting it properly.
 
     Specifically needed for IgniteSprite() anims which can become orphaned from the source sprite (e.g a bullet)
     when the bullet sprite is deleted.
