Subject: [PATCH iwl-next 1/2] ice: make ice_vsi_cfg_rxq() static
Currently, XSK control path in ice driver calls directly
ice_vsi_cfg_rxq() whereas we have ice_vsi_cfg_single_rxq() for that
purpose. Use the latter from XSK side and make ice_vsi_cfg_rxq() static.
ice_vsi_cfg_rxq() resides in ice_base.c and is rather big, so to reduce
the code churn let us move two callers of it from ice_lib.c to
ice_base.c.
