  Log Message:
  -----------
  dpif-netdev: Skip invoking qsort on empty list.

sorted_poll_list() returns the sorted list of rxqs mapped to PMD thread
along with the rxq count. Skip sorting the list if there are no rxqs
mapped to the PMD thread. This can be reproduced with manual pinning and
'dpif-netdev/pmd-rxq-show' command.

Also Clang reports that null argument is passed to qsort in this case.
