[PATCH] ppc/fs2dt: Match function signatures

[Khem Raj]

The prototypes of function pointers is analysed and
compiler finds the signature mismatches and complain about it.

../kexec-tools-2.0.31/kexec/arch/ppc/fs2dt.c:338:44: error: incompatible function pointer types passing 'int (const void *, const void *)' to parameter of type 'int (*)(const struct dirent **, const struct dirent **)' [-Wincompatible-function-pointer-types]
  338 |         numlist = scandir(pathname, &namelist, 0, comparefunc);
      |                                                   ^~~~~~~~~~~
