ice: Move common functions out of ice_main.c part 3/7
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_delete ice_free_res ice_get_res ice_is_reset_recovery_pending ice_vsi_put_qs ice_vsi_dis_irq ice_vsi_free_irq ice_vsi_free_rx_rings ice_vsi_free_tx_rings ice_msix_clean_rings 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>
