vm stuck "deleting" when delete vm after enable iscsi_use_multipath

[MarginHu]

Hi Guys:

I found vm stuck "deleting" when delete vm after enable iscsi_use_multipath. If I set iscsi_use_multipath=False, It's ok when delete vm.

Meanwhile, If I restart nova-compute service on compute node, I will see the "deleting" vm is disappeared on horizon.

version: Ocata.

Environment
===========
# rpm -qa | grep nova
openstack-nova-compute-15.0.3-2.el7.noarch
python2-novaclient-7.1.0-1.el7.noarch

I'd also suggest providing `multipath -ll` output from the compute node after an attempted delete.

In any case this will likely end up being an os-brick issue so I'm looping them in now.

Assuming this is an os-brick issue for now, @lyarwood, any update on this?
