Work with DPDK 16.07, a UNIX socket will be created when we
add vhostuser port. After that, the restarting of ovs-vswitchd
leads to the failure of socket binding, so the vhostuser port
can't be created successfully.
This commit unlink socket file before creating UNIX socket to
avoid failure of socket binding.
