72ede8a12d Set PCM name properly in empty and asym plugins 
The PCM name isn't set properly on empty and asym plugins due to its call
of snd_pcm_open_slave().  Now a new function snd_pcm_open_named_slave()
is created and make snd_pcm_open_slave() an inline function calling the
new one with name=NULL.
