Fixes assert when ReadPixels() called to read from FBO to
GL_PIXEL_PACK_BUFFER, on mip-level > 0, since num_layers
wasn't properly calculated with mip-level.
v2: patched 'iris_create_sampler_view' function instead of
'resolve_sampler_views'. Just like it was suggested in this
function's comment.
The logic of fix is similar to one in 'update_image_surface' function
of i965 driver, which is introduced in commit
f9fd0cf4790cb2a530e75d1a2206dbb9d8af7cb2.
With a slight change: setting array_len=1, like it was done in
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5808 ,
since minifying depth fails KHR-GLES2.texture_3d.filtering tests.
