f2fs: check the largest extent at look-up time
Because of the extent shrinker or other -ENOMEM scenarios, it cannot guarantee that the largest extent would be cached in the tree all the time. Instead of relying on extent_tree, we can simply check the cached one in extent tree accordingly. Reviewed-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
