selftests: mlxsw: Test RIF's reference count when joining a LAG
Test that the reference count of a router interface (RIF) configured for a LAG is incremented / decremented when ports join / leave the LAG. Use the offload indication on routes configured on the RIF to understand if it was created / destroyed. The test fails without the previous patch.
