ASoC: wm8523: fix resource reclaim in wm8523_register error path

This patch includes below fixes:
1. If another WM8523 is registered, need to kfree wm8523 before return -EINVAL.
2. If snd_soc_register_codec failed, goto error path to properly free resources.
3. Instead of using mixed in-line and goto style cleanup, use goto style error
   handling if snd_soc_register_dai failed.
