f654464f7a virStorageSourceIsSameLocation: Special-case storage sources of type 'volume'
The function is used also to compare virStorageSource which may not be
resolved to the image at that point in which case the 'path' is not yet
populated and the actual type is not yet set. This means that the
function fails to consider two identical volume-based disks as pointing
to the same thing.

Add a special case for both images being type=volume in which case we
compare only the pool/volume names.

However, unless the domain is using user aliases (prefixed ua-),
there are no aliases in the persistent definition.

Only match by MAC/PCI/other addresses in that case, to fix update-device

bed0329b1c node_device_conf: Bring variables into loops
I've noticed three functions inside node_device_conf.c, namely:
 - virNodeDeviceCapVPDParseCustomFields()
 - virNodeDeviceCapVPDParseReadOnlyFields()
 - virNodeDeviceCapVPDParseXML()

that have strange attitude towards g_auto* variables. The first
problem is that variables are declared at the top level despite
being used inside a loop. The second problem is use of g_free()
in combination with g_steal_pointer() even though we have
VIR_FREE() which does exactly that.

Bringing variable declarations into their respective loops allows
us to make the code nicer.
