esx: Fall back to path as key when QueryVirtualDiskUuid isn't available

Browse Source 
QueryVirtualDiskUuid is only available on an ESX(i) server. vCenter
returns an NotImplemented fault and a GSX server is missing the
VirtualDiskManager completely. Therefore only use QueryVirtualDiskUuid
with an ESX(i) server and fall back to path as storage volume key for
vCenter and GSX server.
