ASoC: sti: sti_uniperif: add missing error check

Browse Source 
cppcheck warning:

sound/soc/sti/sti_uniperif.c:490:6: style: Variable 'ret' is
reassigned a value before the old one has been
used. [redundantAssignment]
 ret = devm_snd_soc_register_component(&pdev->dev,
     ^
sound/soc/sti/sti_uniperif.c:486:6: note: ret is assigned
 ret = sti_uniperiph_cpu_dai_of(node, priv);
     ^
sound/soc/sti/sti_uniperif.c:490:6: note: ret is overwritten
 ret = devm_snd_soc_register_component(&pdev->dev,
     ^

sti_uniperiph_cpu_dai_of() can return -EINVAL which seems like a
good-enough reason to bail.
