ixgbe: Fix handling of NAPI budget when multiple queues are enabled per vector

Orabug: 23177316

This patch corrects an issue in which the polling routine would increase
the budget for Rx to at least 1 per queue if multiple queues were present.
This would result in Rx packets being processed when the budget was 0 which
is meant to indicate that no Rx can be handled.
