f2fs: Fix format specifier in sanity_check_inode()

f2fs: Fix format specifier in sanity_check_inode()

When building for 32-bit platforms, for which 'size_t' is 'unsigned int',
there is a warning due to an incorrect format specifier:

  fs/f2fs/inode.c:320:6: error: format specifies type 'unsigned long' but the argument has type 'unsigned int' [-Werror,-Wformat]
    318 |                 f2fs_warn(sbi, "%s: inode (ino=%lx) has corrupted i_inline_xattr_size: %d, min: %lu, max: %lu",
        |                                                                                                 ~~~

Use the format specifier for 'size_t', '%zu', to resolve the warning.
