  f2fs: let's avoid panic if extent_tree is not created (2023-01-03 08:59:06 -0800)

----------------------------------------------------------------
f2fs-fix-6.2-rc3

This series fixes the below three bugs introduced in 6.2-rc1.

- fix a null pointer dereference in f2fs_issue_flush, which occurs by the
combination of mount/remount options.

- fix a bug in per-block age-based extent_cache newly introduced in 6.2-rc1,
which reported a wrong age information in extent_cache.

- fix a kernel panic if extent_tree was not created, which was caught by a
wrong BUG_ON.

      f2fs: don't mix to use union values in extent_info
      f2fs: should use a temp extent_info for lookup
