ASoC: codecs: hdac_hdmi: Validate written enum value

hdac_hdmi_set_pin_port_mux() uses the written enum value to index the
texts array before calling snd_soc_dapm_put_enum_double(), which validates
that the value is within the enum item range.

An out-of-range value can therefore make the driver read past the texts
array before the helper rejects the write. Move the lookup after the helper
has accepted the value.
