[PATCH 6.18 386/396] drm/i915/vrr: Check HAS_VRR() first in intel_vrr_is_capable()

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ville Syrjälä <[email protected]>

[ Upstream commit 4b274b0b61ab2a529e5c22e9aa033f3028e639fc ]

There's no point in doing all the other checks in
intel_vrr_is_capable() if the platform doesn't support VRR at all
Check HAS_VRR() before wasting time on the other checks.
