util: fix more coverity warnings

Browse Source 
Coverity doesn't seem to like the new field in the IPAddr struct (used
as explicit padding of the structure) to be left uninitialized, even
though it's never used for anything and is cleared by memset() in
UTI_IPHostToNetwork() before leaving the process.
