It is questionable what we should do with an error in add_dquot_ref(). User
asked us to turn quotas on - that succeeded just fine but then we walked
over already active inodes in add_dquot_ref(), wanted to initialize
accounting information, and that failed for some inode. We can just leave
quota on, the accounting will work for other inodes - that's what we do
now. We could also propagate the failure up and refuse to turn quotas off.
I guess that's a somewhat better approach so if you want to implement that,
go ahead.
