iwlwifi: mvm: fix error checking for multi/broadcast sta 

The earlier patch called the station add functions but didn't
assign their return value to the ret variable, so that the
checks for it were meaningless. Fix that.

Found by smatch:

.../mac80211.c:2560 iwl_mvm_start_ap_ibss() warn: we tested 'ret' before and it was 'false'
.../mac80211.c:2563 iwl_mvm_start_ap_ibss() warn: we tested 'ret' before and it was 'false'
