ALSA: hda/hdmi: Drop bogus check at closing a stream
Some users reported the kernel WARNING with stack traces from hdmi_pcm_close(), and it's the line checking the per_cvt->assigned flag. This used to be a valid check in the past because the flag was turned on/off only at opening and closing a PCM stream. Meanwhile, since the introduction of the silent-stream mode, this flag may be turned on/off at the monitor connection/disconnection time, which isn't always associated with the PCM open/close. Hence this may lead to the inconsistent per_cvt->assigned flag at closing. As the check itself became almost useless and confuses users as if it were a serious problem, just drop the check.
