ASoC: apple: mca: Improve handling of unavailable DMA channels

Browse source

[ Upstream commit fb1847cc46 ]

When we fail to obtain a DMA channel, don't return a blanket -EINVAL,
instead return the original error code if there's one. This makes
deferring work as it should. Also don't print an error message for
-EPROBE_DEFER.
