Subject: [PATCH net 07/11] selftests: mlxsw: Add a test case for VLAN addition
 error flow

Add a test case for the issue fixed by previous commit. In case the
offloading of an unsupported VxLAN tunnel was triggered by adding the
mapped VLAN to a local port, then error should be returned to the user.
