nsupdate: when set to 0, UDP timeout should be calculated by dns_request

Browse source 
The manual page of nsupdate's '-u udptimeout' option states that, quote:

> If zero, the interval is computed from the timeout interval and number
> of UDP retries.

However, nsupdate sets the UDP timeout value to UINT_MAX when it is 0,
thus, not behaving as documented.

Let dns_request_create() calculate the UDP timeout, if it was set to 0.
