NetworkPkg: Fix assert issue in iSCSI driver

The bug is caused by using already freed memory.
If there is already an attempt and execute
'reconnect -r' command, all the AttemptConfig structure
will be freed, but the mCallbackInfo->Current is not
configured as null and this pointer will be used again in
IScsiFormExtractConfig.
