drm/xe: Fix stolen size check to allow equal WOPCM size

Browse Source 
On some platforms without dedicated stolen memory, the calculated
stolen size may be exactly equal to the WOPCM size. The current
assertion incorrectly requires it to be strictly greater, causing
a false failure. Relax the check to allow equality.
