ASoC: tegra20_ac97: Add missing unwind goto in tegra20_ac97_platform_probe()

Smatch Warns:
	sound/soc/tegra/tegra20_ac97.c:321 tegra20_ac97_platform_probe()
	warn: missing unwind goto?

The goto will set the "soc_ac97_ops" and "soc_ac97_bus" operations to
NULL.  But they are already NULL at this point so it is a no-op.
However, just for consistency, change the direct return to a goto.  No
functional change.
