According to the PRM description of the Depth field:
"This field specifies the total number of levels for a volume texture
or the number of array elements allowed to be accessed starting at the
Minimum Array Element for arrayed surfaces"
However, ISL defines array_len as the length of the range
[base_array_layer, base_array_layer + array_len], so it already represents
a value relative to the base array layer like the hardware expects.
This fixes a number of new CTS tests that would crash otherwise:
