drm/i915: Remove driver side BAR release before resize
PCI core handles releasing device's resources and their rollback in case of
failure of a BAR resizing operation. Releasing resource prior to calling
pci_resize_resource() prevents PCI core from restoring the BARs as they
were.
Remove driver-side release of BARs from the i915 driver.
