osmo_mcast_sock: make sure SO_REUSEADDR is applied
virtphy uses UDP multicast to communicate with its osmo-bts-virtual
counterpart. At the momemnt SO_REUSEADDR is not applied for those
multicast connections because OSMO_SOCK_F_UDP_REUSEADDR is not set. This
makes prevents the proper function of UDP multicast.
- Make sure OSMO_SOCK_F_UDP_REUSEADDR is set
