whisper : initialize decoder's rng with unique seed (#2932)

Browse Source 
This change initializes each decoder's random number generator with a
unique seed.

The motivation for this is that currently all decoders are initialized
with the same seed value, 0. The result of this is that for the same
state (logits, probs, and logprobs) they will produce the same output.
