Damage: Don't end speech on death

In Arx Fatalis 1.21. ARX_SPEECH_ReleaseIOSpeech did not work correctly.
This was fixed in commit aac2d8c for Arx Libertatis 1.0.3 because it
left dangling references after entity destruction.

However, ARX_SPEECH_ReleaseIOSpeech also got called on NPC death where
that fix meant that the death scream no longer gets played. Fix that.

Fixes: issue #1579
