ASoC: soc-utils: Add missing va_end in snd_soc_ret()

The default case in snd_soc_ret() use va_start without va_end to cleanup "args" object which can cause undefined behavior. So, add missing va_end to cleanup "args" object.

This is reported by Coverity Scan as "Missing varargs init or cleanup".

I am still not sure how to test this change. Thank you.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks,
Mark
