zink: fix leak when rebinding same image surface

simple way to reproduce this is to run these 4 together:
KHR-GL46.gpu_shader5.images_array_indexing
KHR-GL46.shader_image_load_store.advanced-allMips
KHR-GL46.shader_image_load_store.advanced-sso-simple
KHR-GL46.shader_image_load_store.incomplete_textures
