Fixes#4216
Along with a call to `destroyentities`, this fixes#4271
I'm guessing the intention of this code was to modify the normal spawning of ocelots. However, `cEntity::SpawnOn` is actually called to send the entity to an individual client. That means this code was run for every single player, every time they were sent a chunk with ocelots in it. Thus, the ocelots population would grow exponentially as players log in and move around.
