ASoC: rsnd: Fix an error handling path in 'rsnd_node_count()'

BugLink: https://bugs.launchpad.net/bugs/1951822
[ Upstream commit 173632358fde7a567f28e07c4549b959ee857986 ]

If we return before the end of the 'for_each_child_of_node()' iterator, the
reference taken on 'np' must be released.

Add the missing 'of_node_put()' call.
