iris: fix for tests that blorp after image load store on xe2
This fixes issues seen with following tests:
KHR-GL46.shader_image_load_store.advanced-copyImage
KHR-GL46.shader_image_load_store.advanced-sso-simple
In both cases we are blorping from resource that has been bound as
shader image previously, copy happens when image gets mapped during
glGetTexSubImage.
