Subject: [PATCH 2/5] selftests: net: make ovs-dpctl.py fail when pyroute2 is unsupported

The pmtu.sh kselftest configures OVS using ovs-dpctl.py and falls back
to ovs-vsctl only when ovs-dpctl.py fails. However, ovs-dpctl.py exits
with a success status when the installed pyroute2 package version is
lower than 0.6, even though the OVS datapath is not configured.

As a result, pmtu.sh assumes that the setup was successful and
continues running the test, which later fails due to the missing
OVS configuration.

Fix the exit code handling in ovs-dpctl.py so that pmtu.sh can detect
that the setup did not complete successfully and fall back to
ovs-vsctl.
