pci: Remove redundant parameter from virPCIDeviceBindToStub()

Browse Source 
This internal function supports, in theory, binding to a different
stub driver than the one the PCI device has been configured to use.

In practice, it is only ever called like

  virPCIDeviceBindToStub(dev, dev->stubDriver);

which makes its second parameter redundant. Get rid of it, along
with the extra string copy required to support it.
