drm/xe: Restore pci state upon resume
[ Upstream commit cffa8e83df9fe525afad1e1099097413f9174f57 ]
The pci state was saved, but not restored. Restore
right after the power state transition request like
every other driver.
v2: Use right fixes tag, since this was there initialy, but
accidentally removed.
