This fixes a bug in the netlink path where the vlan_rwsem was not held around __ipoib_vlan_add causing the child_intfs to be manipulated unsafely. In the process this greatly simplifies the vlan_rwsem write side locking to only cover a single non-sleeping statement. This also further increases the safety of the removal ordering by holding the netdev of the parent while the child is active to ensure most bugs become either an oops on a NULL priv or a deadlock on the netdev refcount.
