isl/gen9: Fix array pitch of 3d surfaces

Browse source 
For tiled 3D surfaces, the array pitch must aligned to the tile height.

From the Skylake BSpec >> RENDER_SURFACE_STATE >> Surface QPitch:

   Tile Mode != Linear: This field must be set to an integer multiple of
   the tile height

Fixes CTS tests 'dEQP-VK.pipeline.image.view_type.3d.format.r8g8b8a8_unorm.*'.
Fixes Crucible tests 'func.miptree.r8g8b8a8-unorm.aspect-color.view-3d.*'.
