Subject: [PATCH] f2fs: expose some sectors to user in inline data or dentry
 case
Git-commit: 5b4267d195dd887c4412e34b5a7365baa741b679
Patch-mainline: v4.15-rc1
References: bsc#1052766

If there's some data written through inline data or dentry, we need to shouw
st_blocks. This fixes reporting zero blocks even though there is small written
data.
