ASoC: fix valid stream condition

Browse Source 
[ Upstream commit 6a7c59c6d9 ]

A stream may specify a rate range using 'rate_min' and 'rate_max', so a
stream may be valid and not specify any rates. However, as stream cannot
be valid and not have any channel. Let's use this condition instead to
determine if a stream is valid or not.
