The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).
This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).
