[PATCH 6/9] drm/xe: Remove driver side BAR release before resize

[Ilpo Järvinen]

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 xe driver.
