[dpdk-dev] [PATCH] net/virtio-user: fix crash when detaching device

The rte_eth_dev.data pointer is set to a reference to a static table.
Attempting to rte_free() it leads to a panic. For example, the
following commands result in a panic if run in testpmd
testpmd> port attach virtio_user0,path=/dev/vhost-net,iface=test0
testpmd> port stop 2
testpmd> port close 2
testpmd> port detach 2
