zink: fix crash when restoring sampler-states

When I changed to heap-allocated sampler-objects, I missed the code-path
that restores sampler-states after the blitter; it needs an array of
pointers, not an array of VkSampler objects to behave.

This fixes spec@arb_texture_cube_map@copyteximage for me.
