[PATCH 1/3] PCI/sysfs: Remove resource assignment after BAR resize

["Ilpo Järvinen" <ilpo.jarvinen@linux.intel.com>]

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
__resource_resize_store().
