ASoC: fsl: Fix error handling in pcm030_fabric_probe

Commit Message

This will call twice platform_device_put()
if both platform_device_add() and snd_soc_register_card() fails.
Fix it by using goto label to avoid duplicating the error code logic.

This doesn't apply against current code, please check and resend.
