DevicePathFromTextBBTextCoverage.c function CreateDNSDeviceNode has a
bug, code:

SctStrToIPv4Addr (&IpStr1, (EFI_IPv4_ADDRESS *)(DNS + sizeof (DNS_DEVICE_PATH)));

DNS is a pointer, which is increased by a structure size and converted
to EFI_IPv4_ADDRESS*, which will point to an unknown address. So fix it.

Fixes: 847e0363e846 ("SctPkg: Fix the UefiSct-Wincompatible-pointer-types warnings")

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4712
