We'll be adding a new check in the PRECHANGEUPPER notifier, where we'll
need to check some VLAN uppers. It is hard to do that when there is
already a function named dsa_slave_upper_vlan_check. So rename this one.
Not to mention that this function probably shouldn't have started with
"dsa_slave_" in the first place, since the struct net_device argument
isn't a DSA slave, but an 8021q upper of one.
