ASoC: codecs: nau8360: Fix AB-BA deadlock in mux update
nau8360_dac_mux_put_enum() acquires nau8360->lock before the DAPM mutex,
causing an AB-BA lock inversion. This deadlocks with concurrent stream
startups or mixer updates, which acquire locks in the reverse order.
Fix this by replacing nau8360->lock with the DAPM mutex to protect
pre-checks, releasing it before calling snd_soc_dapm_put_enum_double().
