    kselftest/alsa - conf: Stringify the printed errno in sysfs_get()
    
    [ Upstream commit fd38dd6abda589a8771e7872e4dea28c99c6a6ef ]
    
    GCC 13.2.0 reported the warning of the print format specifier:
    
    conf.c: In function ‘sysfs_get’:
    conf.c:181:72: warning: format ‘%s’ expects argument of type ‘char *’, \
                            but argument 3 has type ‘int’ [-Wformat=]
      181 |                 ksft_exit_fail_msg("sysfs: unable to read value '%s': %s\n",
          |                                                                       ~^
          |                                                                        |
          |                                                                        char *
          |                                                                       %d
    
    The fix passes strerror(errno) as it was intended, like in the sibling error
    exit message.
