ice: Move common functions out of ice_main.c part 5/7
This patch continues the code move out of ice_main.c The following top level functions (and related dependency functions) were moved to ice_lib.c: ice_vsi_clear ice_vsi_close ice_vsi_free_arrays ice_vsi_map_rings_to_vectors Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
