qcacld-3.0: Enable NETIF queues after hdd_roam_register_sta()

Enable NETIF queues after hdd_roam_register_sta().

When there is a race condition where data transmission after
hdd_association_completion and before roam_register_sta, vdev
information passed in the tx_send is a stale entry from the
previous vdev. Enabling queues after roam_register_sta will
fix this issue.
