Fix comparing orb_metadata in uORB::DeviceNode::publish

Browse Source 
Don't compare pointers to metadata, but the metadata contents.

In protected/kernel build there are two sets of metadata, on on kernel
side and another in user side. Thus the comparison of pointers would just
always fail. Compare orb_id instead
