Subject: iavf: free q_vectors before queues in iavf_disable_vf
Patch-mainline: v5.16-rc2
Git-commit: 89f22f129696ab53cfbc608e0a2184d0fea46ac1
References: git-fixes
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")
