selftests: mlxsw: Remove deprecated test
The addition of a VLAN on a bridge slave prompts the driver to have the local port in question join the FID corresponding to this VLAN. Before recent changes, the operation of joining the FID would also mean that the driver would enable VXLAN tunneling if a VXLAN device was also member in the VLAN. In case the configuration of the VXLAN tunnel was not supported, an extack error would be returned. Since the operation of joining the FID no longer means that VXLAN tunneling is potentially enabled, the test is no longer relevant. Remove it.
