Przemyslaw Patynowski 93cb804eda iavf: Fix 'tc qdisc show' listing too many queues 
Fix tc qdisc show dev <ethX> root displaying too many fq_codel qdiscs.
tc_modify_qdisc, which is caller of ndo_setup_tc, expects driver to call
netif_set_real_num_tx_queues, which prepares qdiscs.
Without this patch, fq_codel qdiscs would not be adjusted to number of
queues on VF.
e.g.:
tc qdisc show dev <ethX>
qdisc mq 0: root
qdisc fq_codel 0: parent :4 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent :3 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent :2 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent :1 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
tc qdisc add dev <ethX> root mqprio num_tc 2 map 1 0 0 0 0 0 0 0 queues 1@0 1@1 hw 1 mode channel shaper bw_rlimit max_rate 5000Mbit 150Mbit
tc qdisc show dev <ethX>
qdisc mqprio 8003: root tc 2 map 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
             queues:(0:0) (1:1)
             mode:channel
             shaper:bw_rlimit   max_rate:5Gbit 150Mbit
qdisc fq_codel 0: parent 8003:4 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent 8003:3 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent 8003:2 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent 8003:1 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64

While after fix:
tc qdisc add dev <ethX> root mqprio num_tc 2 map 1 0 0 0 0 0 0 0 queues 1@0 1@1 hw 1 mode channel shaper bw_rlimit max_rate 5000Mbit 150Mbit
tc qdisc show dev <ethX> #should show 2, shows 4
qdisc mqprio 8004: root tc 2 map 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
             queues:(0:0) (1:1)
             mode:channel
             shaper:bw_rlimit   max_rate:5Gbit 150Mbit
qdisc fq_codel 0: parent 8004:2 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
qdisc fq_codel 0: parent 8004:1 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64
