f2fs: fix to use inline space only if inline_xattr is enable
With below mkfs and mount option: MKFS_OPTIONS -- -O extra_attr -O project_quota -O inode_checksum -O flexible_inline_xattr -O inode_crtime -f MOUNT_OPTIONS -- -o noinline_xattr We may miss xattr data with below testcase: - mkdir dir - setfattr -n "user.name" -v 0 dir - for ((i = 0; i < 190; i++)) do touch dir/$i; done - umount - mount - getfattr -n "user.name" dir user.name: No such attribute The root cause is that we persist xattr data into reserved inline xattr space, even if inline_xattr is not enable in inline directory inode, after inline dentry conversion, reserved space no longer exists, so that xattr data missed. Let's use inline xattr space only if inline_xattr flag is set on inode to fix this iusse.
