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
