fm10k: Fix handling of NAPI budget when multiple queues are enabled per vector

[ Upstream commit 9f872986479b6e0543eb5c615e5f9491bb04e5c1 ]

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.
