ASoC: codecs: aw88395: initialize cur_scene_id to 0

cppcheck reports
sound/soc/codecs/aw88395/aw88395_lib.c:789:6: error: Uninitialized variable: cur_scene_id [uninitvar]
 if (cur_scene_id == 0) {
     ^

Passing a garbage value to aw_dev_parse_data_by_sec_type_v1() will cause a crash
when the value is used as an array index.  This check assumes cur_scene_id is
initialized to 0, so initialize it to 0.
