[ALSA] ak4114 - Fix possible Oops with callbacks

Browse source

ak4114 code may trigger Oops when the parameters are changed without
call of snd_ak4114_build().  Now it checks the existence of kctl
element, and the workq is triggered after building the necessary
kcontrols.
Also, did some code clean up.
