Fix for bug #1415936 Bug #1415936:host name is blank for mxosrvr INFO log. To fix it ,call host_addr_get to get host name no matter whether -TCPADD is set or not. If TCPADD is set and different with the ip returned by host_addr_get,TCPADD is used and host name is set to "UNRESOLVED". If TCPADD is set and same with the ip returned by host_addr_get, TCPADD is used and host name is set from host_addr_get. If TCPADD is not set ,ip and host name are set from host_addr_get.
