Parsing can acquire port range registers via\nmlxsw_sp_flower_parse_ports_range(), but since this rulei never goes\nthrough mlxsw_sp_acl_rulei_destroy(), those registers were never\nreleased, including through chain template deletion.\n\nFactor out of mlxsw_sp_acl_rulei_destroy() the code to actually\nrelease the necessary resources and call from\nmlxsw_sp_flower_tmplt_create() to plug the leak.\n\nThe issue was found during a review of Wentao Liang's patch referenced\nbelow."
