netdev-dpdk: Fix a bug in netdev_dpdk_set_multiq().

Commit 5a0340 (dpif-netdev: Create multiple tx/rx queues when
adding dpdk interface.) introduced a bug which causes the function
netdev_dpdk_set_multiq() never resetting the tx queues.  This bug
could cause pmd thread accessing unassigned memory, resulting in
segfault.

This commit fixes the bug.
