Subject: [PATCH iwl-next 2/2] ice: make ice_vsi_cfg_txq() static
Currently, XSK control path in ice driver calls directly
ice_vsi_cfg_txq() whereas we have ice_vsi_cfg_single_txq() for that
purpose. Use the latter from XSK side and make ice_vsi_cfg_txq() static.
ice_vsi_cfg_txq() resides in ice_base.c and is rather big, so to reduce
the code churn let us move the callers of it from ice_lib.c to
ice_base.c.
This change puts ice_qp_ena() on nice diet due to the checks and
operations that ice_vsi_cfg_single_{r,t}xq() do internally.
