netdev-dpdk: Assign socket id according to device's numa id
We can hotplug attach DPDK ports specified via the 'dpdk-devargs'
option now.
But the socket id of DPDK ports can't be assigned correctly,
it is always 0. The socket id of DPDK ports should be assigned
according to the numa id of the device.
Fixes: 55e075e65ef9e ("netdev-dpdk: Arbitrary 'dpdk' port naming")
