From: Liu Bo <bo.li.liu@oracle.com>
Subject: Btrfs-progs: convert: do not clear nodatasum flag in inode item
Git-commit: 188f9c889a062307cf18fdacf91381f29f12bf6d
Patch-mainline: v4.11.1
References: bsc#1042369

With the current btrfs-convert, if we convert a ext4 without data checksum,
it'd not set nodatasum flag in inode item, nor create csum item, reading
file ends up with checksum errors.
