f2fs: read page index before freeing
commit 0ea295dd853e0879a9a30ab61f923c26be35b902 upstream.
The function truncate_node frees the page with f2fs_put_page. However,
the page index is read after that. So, the patch reads the index before
freeing the page.
Fixes: bf39c00a9a7f ("f2fs: drop obsolete node page when it is truncated")
