[ALSA] Fix substream selection in PCM and rawmidi
The PCM and rawmidi substreams can be selected explicitly by opening
control handle and set via *_PREFER_SUBDEVICE ioctl. But, when
multiple controls are opened, the driver gets confused.
The patch fixes the initialization of prefer_*_subdevice and the
check of multiple controls. The first set subdevice is picked up
as the valid one.
