CLOUDSTACK-6146. [VMware] [ESXi 5.5] Live storage migration of an already migrated volume fails

Browse Source 
In vCenter 5.5, once a volume is migrated the VMDKs are renamed to match the name of the VM.
If a volume has been renamed upon migration update its volumePath to that of the new disk filename.
