batman-adv: fix warning in function batadv_v_elp_get_throughput
When CONFIG_CFG80211 isn't enabled the compiler correcly warns about
'sinfo.pertid' may be unused. It can also happen for other error
conditions that it not warn about.
net/batman-adv/bat_v_elp.c: In function ‘batadv_v_elp_get_throughput.isra.0’:
include/net/cfg80211.h:6370:13: warning: ‘sinfo.pertid’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
kfree(sinfo->pertid);
~~~~~^~~~~~~~
Rework so that we only release '&sinfo' if cfg80211_get_station returns
zero.
