drm/i915/gtt: Fix pte clear range
Comparing pte index to a number of entries is wrong
when clearing a range of pte entries. Use end marker
of 'one past' to correctly point adequate number of
ptes to the scratch page.
v2: assert early instead of warning late (Chris)
v3: removed consts (Joonas)
Fixes: d209b9c3cd28 ("drm/i915/gtt: Split gen8_ppgtt_clear_pte_range")
