i965/hiz/gen6: Stop setting false qpitch 

which is not applicable for "all slices at each lod". Current
logic makes one to believe it has some purpose. When miptree
layout is calculated brw_miptree_layout_texture_array() sets
the qpitch unconditionally but later on ignores it altogether
for ALL_SLICES_AT_EACH_LOD.
