winsys/radeon: fix bo with virtual address referencing mismatch

If the same context try to flink and open the object, use the
same bo struct instead of opening a new gem handle for the object.
This way we avoid avoid having 2 different handle pointing to the
same kernel object which can latter lead to trouble with virtual
address.
