[PATCH 2/3] drm/xe: Remove driver side resource assignment after BAR resize

[Ilpo Järvinen]

pci_resize_resource() assigns the resized BAR and the other BARs it
released, or restores the original configuration on failure. Calling
pci_assign_unassigned_bus_resources() after it is redundant. If that
call manages to assign more resources in some scenario, the problem
should be fixed inside pci_resize_resource() instead.

Remove the pci_assign_unassigned_bus_resources() call from
xe_pci_rebar_resize().
