[PATCH 1/2] virNetDevTapCreate: Use error message hinting to multiqueue use only when opening multiple queues
From: Peter Krempa <pkrempa(a)redhat.com>
Due to a logic bug the error message mentioning mult_queue operation
would be mentioned also when a single queue would be opened on an
externally managed tap device.
Adjust the condition to trigger only when multiple queues are in use.
