From: Nicholas Nunley <nicholas.d.nunley@intel.com>

iavf_free_queues() clears adapter->num_active_queues, which
iavf_free_q_vectors() relies on, so swap the order of these two function
calls in iavf_disable_vf(). This resolves a panic encountered when the
interface is disabled and then later brought up again after PF
communication is restored.

Fixes: 65c7006f234c ("i40evf: assign num_active_queues inside i40evf_alloc_queues")
