Jakub Kicinski ecc391a541 netdev: fix repeated netlink messages in queue stats
The context is supposed to record the next queue to dump,
not last dumped. If the dump doesn't fit we will restart
from the already-dumped queue, duplicating the message.

Before this fix and with the selftest improvements later
in this series we see:

  # ./run_kselftest.sh -t drivers/net:stats.py
  timeout set to 45
  selftests: drivers/net: stats.py
  KTAP version 1
  1..5
  ok 1 stats.check_pause
  ok 2 stats.check_fec
  ok 3 stats.pkt_byte_sum

  not ok 4 stats.qstat_by_ifindex
  ok 5 stats.check_down
  # Totals: pass:4 fail:1 xfail:0 xpass:0 skip:0 error:0

With the fix:

  # ./ksft-net-drv/run_kselftest.sh -t drivers/net:stats.py
  timeout set to 45
  selftests: drivers/net: stats.py
  KTAP version 1
  1..5
  ok 1 stats.check_pause
  ok 2 stats.check_fec
  ok 3 stats.pkt_byte_sum
  ok 4 stats.qstat_by_ifindex
  ok 5 stats.check_down
  # Totals: pass:5 fail:0 xfail:0 xpass:0 skip:0 error:0
