iris: Pick the right BO in iris_resource_get_param

Browse source 
Pick the clear color BO if the clear color plane is being queried. This
avoids picking a NULL aux BO on XeHP.

When creating shared resources, we place the gallium-visible planes in
the same buffer object. However, when importing them, we aren't very
strict about each plane sharing the same BO. So, instead of just using
res->bo, we use a couple ternaries to figure out the right one.
