ac: fix the number of coordinates for ac_image_get_lod and arrays

This fixes crashes for the following CTS:
dEQP-VK.glsl.texture_functions.query.texturequerylod.*

Cubemaps are the same as 2D arrays.

Fixes: 625dcbbc456 ("amd/common: pass address components individually to
ac_build_image_intrinsic")
