mlxsw: spectrum_acl: Support rule creation without action creation
Up until now, when ACL rule was created its action was created with it. It suits well for tc flower where ACL rule always needs an action, however it does not suit multicast router, where the action is created prior to setting a route, which in Spectrum-2 is actually an ACL rule. Add support for rule creation without action creation. Do it by adding afa_block argument to mlxsw_sp_acl_rule_create, which if NULL then an action would be created, also add an indication within struct mlxsw_sp_acl_rule_info that tells if the action should be destroyed when the rule is destroyed.
