net: ll_temac: Do not make promiscuous mode sticky on multicast
When user has requested IFF_ALLMULTI or have set more than 4 multicast addresses, we should just use promiscuous mode, but not set it in flags, as it causes the interface to stay in promiscuous mode even when the non-IFF_PROMISC condition that caused promiscuous mode to be enabled has gone away.
