> releasing VSI
> 
> Before releasing the VSI, remove the VSI scheduler node. If not, the node is
> left in the scheduler tree and, on subsequent load, the scheduler tree
> contains the node so it does not set it in vsi_ctx.
> This, later, causes the node to not be found in ice_sched_get_free_qparent
> which leads to a "Failed to set LAN Tx queue context, error: -1".
> 
> To remove the scheduler node, this patch introduces ice_rm_vsi_lan_cfg and
> related helpers.
