net: Zero sockaddr_in in parse_host_port()
We don't currently zero-initialize the 'struct sockaddr_in' that
parse_host_port() fills in, so any fields we don't explicitly
initialize might be left as random garbage. POSIX states that
implementations may define extensions in sockaddr_in, and that those
extensions must not trigger if zero-initialized. So not zero
initializing might result in inadvertently triggering an impdef
extension.
memset() the sockaddr_in before we start to fill it in.
Fixes: Coverity CID 1005338
