[libvirt] [PATCH] conf: fix cannot start a guest have a shareable network iscsi hostdev

[Luyao Huang]

https://bugzilla.redhat.com/show_bug.cgi?id=1174569

We should do nothing for the shareable network iscsi hostdev in
qemuAddSharedHostdev and qemuRemoveSharedHostdev. Shareable for
a network iscsi hostdev is not valid, so just ignore it.
