ixgbevf: Fix handling of NAPI budget when multiple queues are enabled per vector
[ Upstream commit d0f71afffa1c3d5a36a4a278f1dbbd2643176dc3 ]
This is the same patch as for ixgbe but applied differently according to
busy polling. See commit 5d6002b7b822c74 ("ixgbe: Fix handling of NAPI
budget when multiple queues are enabled per vector")
