netdev-linux: Don't log vport warnings when kernel datapath not loaded.
The *_get_stats functions call get_stats_via_vport(), which tries to get
information about ports attached to the kernel datapath. When a pure
userspace switch is used (eg, the OVS kernel module isn't loaded), ports
are not attached to a kernel datapath, so warnings get logged. This
commit handles that case and doesn't log a warning. However, if the
kernel datapath is loaded, ports attached to a userspace datapath will
still log a warning.
