qlcnic: Set real_num_{tx|rx}_queues properly

Browse source 
Do not set netdev->real_num_tx_queues directly,
let netif_set_real_num_tx_queues() take care of it.
Do not overwrite netdev->num_tx_queues everytime when driver
changes its Tx ring size through ethtool -L and also notify
stack to update number of Rx queues.
