    common/cnxk: fix base rule merge

    Egress rules do not have a base steering rule and the
    current base steering rule is applicable only for ingress
    rules. Hence, when creating a flow rule, merge base steering
    rule only for ingress rules.

    Fixes: f9af9080746 ("common/cnxk: add mcam utility API")
