s4:dcesrv_netr_DsRAddressToSitenamesExW - fix the detection of the address family...

Obviously the last attempt wasn't enough. Now we do really only read the first
byte in the address buffer which on little endian transmission does always
contain the address family (MS-NRPC 2.2.1.2.4.1).
This should now be working platform-independently.
