We have to keep data for roll-forward recovery. Without this patch, we're
able to lose there-in data by quota overwrites.

When I test por_fsstress case w/ quota feature enabled, I suffer below error
during repair:
Info: superblock features = f8 : extra_attr project_quota inode_checksum
flexible_inline_xattr quota_ino
Info: superblock encrypt level = 0, salt = 00000000000000000000000000000000

ioctl for device
[ERROR] quotaio_tree.c:110:get_free_dqblk:: Cannot allocate new quota block (out
of disk space).
I found new_data_block() will reject block allocation on an unclean umounted
image, result in quota file repair failure.
With current implementation, I think we should mount that image again for
recovery, then umount and run fsck on it again to repair quota file.
However, user didn't be noticed that how to fix this... I know there is no such
report tho, I think we'd better fix this case in fsck, any thoughts? let
allocation skip fsynced datas?
Thanks,

Actually, that was my TODO, but I had no time to fix it, but had to stop it to
avoid further corruption.

Copied, maybe I can help to fix it. It looks it will be easy to skip fsyned
datas during block allocation than porting recovery flow from kernel to tools.
