This was reported by syzkaller, which used a 4k name. Limit the name to something reasonable, I randomly picked 128.

Given the return value vlan_get_encap_level() we need to store the nest level of the bond device, and then compare the vlan's encap level to this. Without this, this check always fails and learning packets are never sent. In addition, this same commit caused a regression in the behavior of balance_alb, which requires learning packets be sent for all interfaces using the slave's mac in order to load balance properly. For vlan's that have not set a user mac, we can send after checking one bit. Otherwise we need send the set mac, albeit defeating rx load balancing for that vlan.
