virtio_net: Fix out of bounds access of sq
[ Upstream commit 1667c08a9d31c7cdf09f4890816bfbf20b685495 ]
When XDP is disabled, curr_queue_pairs + smp_processor_id() can be
larger than max_queue_pairs.
There is no guarantee that we have enough XDP send queues dedicated for
each cpu when XDP is disabled, so do not count drops on sq in that case.
Fixes: 5b8f3c8d30a6 ("virtio_net: Add XDP related stats")
