These snd_BUG_ON() can never trigger, so just remove them to save a few
LoC.

This patch is speculative. Maybe the other "if"s should be removed and the
error code returned instead.
I chose to remove these ones and the corresponding error code, because it
seems that it is already handled this way in hdmi_pcm_open().
I don't know the code enough, so it is only my guess.
Review with care :)
