NetworkPkg:Fix iSCSI driver issue to work with iSCSI LIO target 

The patch fixes iSCSI driver can't reinstate itself when configured
 in AutoConfigure mode and IPv6 stack is actually used.
The issue occurs when iSCSI driver communicates with
iSCSI LIO target in IPv6 path and the target sends
back TCP FIN packets randomly.
