ASoC: rsnd: care return value from rsnd_node_fixed_index()

Browse source 
[ Upstream commit d09a7db431 ]

Renesas Sound is very complex, and thus it needs to use
rsnd_node_fixed_index() to know enabled pin index.

It returns error if strange pin was selected,
but some codes didn't check it.

This patch 1) indicates error message, 2) check return
value.
