[ovs-dev] [PATCH 2/2] dpif-netlink: Only warn when OVS module unloaded when using DPDK netdev

[Ciara Loftus]

Change the log level from error to warning when reporting that the
openvswitch module is not loaded but the DPDK netdev is initialised.
OVS using DPDK can still function correctly without the module loaded.
