Description of problem:
-----------------------
The qemu-kvm crashed while removing the storage domain via RHV-M. The storage domain has few vm's running on it. This was seen on a dedupe and compression enabled (VDO) storage domain


Version-Release number of selected component (if applicable):
-----------------------------------------------------------
qemu-guest-agent-2.8.0-2.el7.x86_64
qemu-kvm-rhev-2.10.0-21.el7_5.4.x86_64
qemu-kvm-common-rhev-2.10.0-21.el7_5.4.x86_64
libvirt-daemon-driver-qemu-3.9.0-14.el7_5.6.x86_64
qemu-img-rhev-2.10.0-21.el7_5.4.x86_64
glusterfs-3.8.4-54.13.el7rhgs.x86_64

How reproducible:
----------------

Steps to Reproduce:
-------------------
1. Have the HE deployed on a Hyperconverged infrastructure(RHHI)
2. Create a storage domain with VDO enabled volumes
3. Create multiple vm's and pump data using FIO
4. Stop the gluster volumes and delete it
5. Remove the storage domain via RHV-M

Actual results:
--------------
qemu-kvm crashed

Expected results:
----------------
qemu-kvm shouldn't crash

Additional info:
----------------
1.This was seen on a gluster replica 3 (1*3) volume
2.Had VDO enabled bricks 
3.3 node cluster
