vlan: updates vlan real_num_tx_queues
Updates real_num_tx_queues in case underlying real device
has changed real_num_tx_queues.
-v2
As per Eric Dumazet<eric.dumazet@gmail.com> comment:-
-- adds BUG_ON to catch case of real_num_tx_queues exceeding num_tx_queues.
-- created this self contained patch to just update real_num_tx_queues.
