ASoC: wm_adsp_fw_find_test: Fix missing NULL terminator on file name list

Browse source

The array wm_adsp_fw_find_test_dir_all_files[] needs a NULL terminator.

It was documented at line 41 that dir_files points to a NULL-terminated
array.

   /* NULL-terminated array of pointers to filenames ... <snip> */
   const char * const *dir_files;

This fixes the error reported by KASAN:
