ASoC: sma1307: fix uninitialized variable refence

When firmware loading is disabled, gcc warns that the local
'fw' variable fails to get initialized:

sound/soc/codecs/sma1307.c: In function 'sma1307_setting_loaded.isra':
sound/soc/codecs/sma1307.c:1717:12: error: 'fw' is used uninitialized [-Werror=uninitialized]
 1717 |         if (!fw) {
      |            ^
sound/soc/codecs/sma1307.c:1712:32: note: 'fw' was declared here
 1712 |         const struct firmware *fw;

Check the return code from request_firmware() to ensure that the
firmware is correctly set, and drop the incorrect release_firmware()
on that uninitialized data.
