quota: marker accounting goes bad with rename while writing a file

This is a backport of http://review.gluster.org/#/c/11403/

> With below test-case, marker accounting becomes bad:
> 1) Create a volume with 1 brick
> 2) fuse mount
> 3) on one terminal write some data
>    dd if=/dev/zero of=f1 bs=1M count=500 oflag=sync
> 4) on another terminal execute below rename operation while the write is
> still in progress
>     for i in {1..50}; do
>         ii=`expr $i + 1`;
>         mv f$i f$ii;
>     done
>
> remove-xattr is already on while doing rename operation,
> we should not be doing again in background when reducing the
> parent size.
