mac80211: remove unnecessary num_mcast_sta check
Checking for num_mcast_sta in __ieee80211_request_smps_ap() is
unnecessary as sta list will be empty in this case anyway, so
the list iteration will just exit immediately. Since this isn't
a "hot" code path, it doesn't really matter, and the next patch
will redefine num_mcast_sta to make this check invalid.
