[ALSA] ymfpci: fix volume handling of the 44.1 kHz slot
The existing code for handling the 44.1 slot's volume has two problems: the volume is not affected by the 'Wave Playback Volume' mixer control, and the BUF441OUTVOL register, which is used to control the per- substream volume for this slot, uses a different scale than the gain fields of the other slots. This patch makes the BUF441OUTVOL register a shadow of the NATIVEDACOUTVOL register so that the Wave volume is consistent for all substreams. As a consequence of this, the per-substream PCM volume control gets no longer activated for the substream using this slot. The code for (de)activating the mixer control is moved from the open/close to the prepare/trigger_stop callbacks so that it is able to determine the substream's slot.
