i40e: mark expected switch fall-through

drivers/net/ethernet/intel/i40e/i40e_xsk.c:217:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   bpf_warn_invalid_xdp_action(act);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/intel/i40e/i40e_xsk.c:218:2: note: here
  case XDP_ABORTED:
