[net-next 1/9] ixgbevf: Fix handling of NAPI budget when multiple queues are enabled per vector

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: William Dauchy <william@gandi.net>

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")
