netxen: fix netxen_nic_poll() logic
[ Upstream commit 6088beef3f7517717bd21d90b379714dd0837079 ]
NAPI poll logic now enforces that a poller returns exactly the budget
when it wants to be called again.
If a driver limits TX completion, it has to return budget as well when
the limit is hit, not the number of received packets.
