[PATCH 04/21] net: thunderx: Set queue count based on number of CPUs

81xx has only 4 CPUs, so it doesn't make sense to initialize entire Qset i.e 8
queues by default. Made changes to queue initialization to init queues equal to
number of CPUs or
8 queues whichever is lesser. Also this will be applicable to VMs with VNIC VF
attached and having less VCPUs

...

-	qcount = MAX_CMP_QUEUES_PER_QS;
+	qcount = min_t(int, MAX_CMP_QUEUES_PER_QS, num_online_cpus());

We have netif_get_num_default_rss_queues() which does this.
