When converting our DSS masks to bitmaps, we fumbled the condition used
to check whether any DSS are present in the first gslice. Since
intel_sseu_find_first_xehp_dss() returns a 0-based number, we need a >=
condition rather than >.
Fixes: b87d39019651 ("drm/i915/sseu: Disassociate internal subslice mask representation from uapi")
