Subject: [PATCH v4] ALSA: ice1712: consider error value

earlier we were ignoring the return value of snd_ak4114_create and
always returning 0.
now we are returning the actual status. revo_init is calling this
function, and revo_init is checking the return value.

change in v3: spec->ak4114 is now dereferenced if we dont get an
error value from snd_ak4114_create.

change in v4: error value returned according to coding style.
