Subject: [PATCH v1 2/4] kselftest: alsa: Fix the printf format specifier in call to ksft_print_msg()

The GCC 13.2.0 compiler issued the following warning:

mixer-test.c: In function ‘ctl_value_index_valid’:
mixer-test.c:322:79: warning: format ‘%lld’ expects argument of type ‘long long int’, \
			      but argument 5 has type ‘long int’ [-Wformat=]
  322 |                         ksft_print_msg("%s.%d value %lld more than maximum %lld\n",
      |                                                                            ~~~^
      |                                                                               |
      |                                                                               long long int
      |                                                                            %ld
  323 |                                        ctl->name, index, int64_val,
  324 |                                        snd_ctl_elem_info_get_max(ctl->info));
      |                                        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |                                        |
      |                                        long int

Fixing the format specifier as advised by the compiler suggestion removes the
warning.
