Fix an off-by-one error after StreamAndUpdateEOS() to remove the MSAN warning about reading an uninitialized variable in the kv_cache.
...
The logic for choosing whether or not to attend to the last token during prefill wasn't completely consistent with StreamAndUpdateEOS(), causing an off-by-one error that prevented the kv_cache from being fully populated.
