sfc: check recirc_id match caps before MAE offload

Offloaded TC rules always match on recirc_id in the MAE, so we should
 check that the MAE reported support for this match before attempting
 to insert the rule.
These checks allow us to fail early, avoiding the PCIe round-trip to
 firmware for an MC_CMD_MAE_ACTION_RULE_INSERT that will only fail,
 and more importantly providing a more informative error message that
 identifies which match field is unsupported.
