drm/i915/opregion: rvda is relative from opregion base in opregion 2.1+
Starting from opregion version 2.1 (roughly corresponding to ICL+) the
RVDA field is relative from the beginning of opregion, not absolute
address.
Fix the error path while at it.
v2: Make relative vs. absolute conditional on the opregion version,
bumped for the purpose. Turned out there are machines relying on
absolute RVDA in the wild.
v3: Fix the version checks
