[libvirt] [PATCH 2/2] check whether the vm is paused before setting it offline

[Wen Congyang <wency cn fujitsu com>]

If we do not performe a live migration, the vm is always paused when we go to
doPeer2PeerMigrate2() and doPeer2PeerMigrate3(), because we stop the vm in
qemuMigrationPerform(). So we should check it before setting it offline.
