This new test case checks whether we are handling NVDIMMs

As of v9.8.0-rc1~7 we check whether two <memory/> devices don't
overlap (since we allow setting where a <memory/> device should
be mapped to). We do this pretty straightforward, by comparing
start and end address of each <memory/> device combination.
But since only the start address is given (an exposed in the
XML), the end address is computed trivially as:
start + mem->size * 1024
And for majority of memory device types this works. Except for
NVDIMMs. For them the <memory/> device consists of two separate
regions: 1) actual memory device, and 2) label.
Label is where NVDIMM stores some additional information like
namespaces partition and so on. But it's not mapped into the
guest the same way as actual memory device. In fact, mem->size is
a sum of both actual memory device and label sizes. And to make
things a bit worse, both sizes are subject to alignment (either
the alignsize value specified in XML, or system page size if not
specified in XML).
Therefore, to get the size of actual memory device we need to
take mem->size and substract label size rounded up to alignment.
If we don't do this we report there's an overlap between two
NVDIMMs even when in reality there's none.

commit v9.10.0-129-g8b93d78c83 (first appearing in libvirt-10.0.0) was
supposed to allow forcing a PCI hostdev to be bound to a particular
driver by adding <driver model='blah'/> to the XML for the
device. Unfortunately, a single line was missed during the final
changes to the patch prior to pushing, and the result was that the
driver model could be set to *anything* and it would be accepted but
just ignored.
This patch adds the missing line, which will set the stubDriverName
field of the virPCIDevice object from the hostdev object as the
virPCIDevice is being created. This ends up being used by
virPCIDeviceBindToStub() as the driver that it binds the device to.
