selftests: mlxsw: Reduce running time using offload indication

Browse Source 
After adding a given number of flower rules for different IPv6
addresses, the test generates traffic and ensures that each packet is
received, which is time-consuming.

Instead, test the offload indication of the tc flower rules and reduce
the running time by half.
