[PATCH net] net: mvpp2: cls: Fix leaked ethtool_rx_flow_rule

[Maxime Chevallier]

The flow_rule is only used when configuring the classification tables,
and should be free'd once we're done using it. The current code only
frees it in the error path.

Fixes: 90b509b39ac9 ("net: mvpp2: cls: Add Classification offload support")
