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().

ASoC: codecs: nau8360: Block DSP path selection when firmware load fails

Block the DSP path selection if the firmware fails to load to prevent
invalid routing states.

If the firmware is not ready, nau8360_dac_mux_put_enum() will print
a rate-limited warning and return -EBUSY. This rejects the invalid
userspace request and maintains the original hardware state without
causing audio wrong status.
