Heyi Guo 764c9d9551 MdeModulePkg/Ip4Dxe: fix ICMP echo reply memory leak 
When UEFI receives ICMP echo packets it will enter Ip4IcmpReplyEcho
function, and then call Ip4Output. However, if Ip4Output gets some
error and exits early, e.g. fails to find the route entry, memory
buffer of "Data" gets no chance to be freed and memory leak will be
caused. If there is such an attacker in the network, we will see UEFI
runs out of memory and system hangs.

So we explicitly free the memory when error status is returned.
