Previously all memory objects were mapped with read-write access whenever they were requested on host so that they were fully accessible on host until their unmapping. This patch changes this behaviour: now memory objects are mapped with just the required access mode. If an incompatible access mode is requested on host afterwards, the object is remapped.
