The kfree() function was called in one case by the batadv_dat_forward_data() function during error handling even if the passed variable contained a null pointer. This issue was detected by using the Coccinelle software.
* Thus return directly after a batadv_dat_select_candidates() call failed at the beginning.
* Delete the label “out” which became unnecessary with this refactoring.
