commit 4d820543c54c47a2bd3c95ddbf52f83c89a219a0 upstream.

When using vf_ops->ndo_select_queue, the number of queues of VF is
usually bigger than the synthetic NIC. This condition may happen
often.
Remove "unlikely" from the comparison of ndev->real_num_tx_queues.

Fixes: b3bf5666a510 ("hv_netvsc: defer queue selection to VF")
