ASoC: hdac_hdmi: Remove temporary string use in create_fill_jack_kcontrols

There is no need to use temporary strings to construct the kcontrol names,
devm_kasprintf can be used to replace the snprintf + devm_kstrdup pairs.

This change will also fixes the following compiler warning/error (W=1):

sound/soc/codecs/hdac_hdmi.c: In function ‘hdac_hdmi_jack_port_init’:
sound/soc/codecs/hdac_hdmi.c:1793:63: error: ‘ Switch’ directive output may be truncated writing 7 bytes into a region of size between 1 and 32 [-Werror=format-truncation=]
 1793 |                         snprintf(kc_name, sizeof(kc_name), "%s Switch", xname);
      |                                                               ^~~~~~~

cc1: all warnings being treated as errors

The warnings got brought to light by a recent patch upstream:
commit 6d4ab2e97dcf ("extrawarn: enable format and stringop overflow warnings in W=1")
