drm/i915/xehp: Fix missing sentinel on mcr_ranges_xehp
There's a missing sentinel since we are not using ARRAY_SIZE(), but rather
checking that the .start is 0 to stop the iteration in mcr_range().
BUG: KASAN: global-out-of-bounds in mcr_range.isra.0+0x69/0xa0 [i915]
Read of size 4 at addr ffffffffa0889928 by task modprobe/3881
