> pci_disable_sriov if the VFs are not assigned. This was causing the
> VIRTCHNL_OP_DISABLE_QUEUES to fail because it was trying to stop the

> Fix this by calling pci_disable_sriov before stopping the Tx/Rx queues.
> This allows the VIRTCHNL_OP_DISABLE_QUEUES to get processed before the
> driver tries to stop the Rx/Tx queues in ice_free_vfs.
