Subject: [PATCH 104/129] quota: fix double accounting with rename operation

This is a backport of http://review.gluster.org/#/c/11264/

> When a rename operation is performed, we are renaming
> the file first and performing remove-xattr when reducing
> the contri size from parents.
> This remove-xattr fails as the file is alreday renamed,
> this failure causes reduce-parent-size to abort resulting
> in double quota accounting
>
> This patch fixes the problem. We don't need to perform remove-xattr
> operation on a file when performing reduce-parent-size txn as this
> will be alreday done before starting reduce-parent-size txn
>
