batman-adv: Return directly after a failed batadv_dat_select_candidates() in batadv_dat_forward_data()
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.
