Chao Yu e34438c903 f2fs: fix to do sanity check with node footer and iblocks 
This patch adds to do sanity check with below fields of inode to
avoid reported panic.
- node footer
- iblocks

https://bugzilla.kernel.org/show_bug.cgi?id=200223

- Overview
BUG() triggered in f2fs_truncate_inode_blocks() when un-mounting a mounted f2fs image after writing to it

- Reproduce

- POC (poc.c)

static void activity(char *mpoint) {

  char *foo_bar_baz;
  int err;

  static int buf[8192];
  memset(buf, 0, sizeof(buf));

  err = asprintf(&foo_bar_baz, "%s/foo/bar/baz", mpoint);

  // open / write / read
  int fd = open(foo_bar_baz, O_RDWR | O_TRUNC, 0777);
  if (fd >= 0) {
    write(fd, (char *)buf, 517);
    write(fd, (char *)buf, sizeof(buf));
    close(fd);
  }

}

int main(int argc, char *argv[]) {
  activity(argv[1]);
  return 0;
}
