[cgutman] 45016: - Unlock the address file before calling IPSendDatagram - We don't need to be locked anymore at that point and it also causes problems with loopback packets - Use the TTL value stored in the address file for ICMP packets

Log:
 - Unlock the address file before calling IPSendDatagram
 - We don't need to be locked anymore at that point and it also causes problems with
loopback packets
 - Use the TTL value stored in the address file for ICMP packets
