examples/netmap_compat: fix infinite loop

Infinite loop: The loop does not have a normal termination condition,
so will continue until an abnormal condition arises.
In rte_netmap_poll: Infinite loop with unsatisfiable exit condition.

Coverity issue: 30701
Fixes: 06371afe ("examples/netmap_compat: import netmap compatibility example")
