librpc: fixed the GUID_compare() function
When comparing two unsigned values you can't just subtract them. Imagine you are comparing: "uint32_t u1" and "uint32_t u2". If you use "u1 - u2" and u2 is zero, then the signed integer result will depend on the top bit of u1. This error occurs in a few places in Samba. For DRS replication it resulted in corrupt uptodateness vectors.
