Subject: [PATCH] ASoC: Remove locking in snd_soc_{new,free}_ac97_codec()

snd_soc_new_ac97_codec() and snd_soc_free_ac97_codec() are called from
within a CODEC's probe() and remove() callbacks. Those will not run
concurrently against each other for the same CODEC instance, hence it is not
necessary to protect the two functions with a mutex.

This removes the last user in the ASoC core of the snd_soc_codec mutex field
and will allow us to eventually remove it.
