drm/xe: Add warn when level can not be zero.

Browse Source 
At xe_pt_zap_ptes_entry() and xe_pt_stage_unbind_entry, the level cannot
be 0. Therefore, add an independent check for the level. Since the level
cannot be zero at this point, there is no need to check for `is_compact`,
so remove that instead.
