drm/i915/vrr: Fix intel_vrr_dcb_vmin_vblank_start()
intel_vrr_dcb_vmin_vblank_start() may evaluate
intel_vrr_dcb_vmin_vblank_start_next() twice, and given that
this is doing hardware access under the hood isn't really
desired.
Even worse, the double evaluation might even cause
intel_vrr_dcb_vmin_vblank_start() itself to finally
return -EINVAL (if we race against the DMC hard enough),
which we definitely never want to do.
Eliminate the double evaluation, guaranteeing a sane
final return value at the same time.
