mac80211: call get_expected_throughput only after adding station
Depending on which method the driver implements, userspace could call this (indirectly, by getting station info) before the driver knows about the station, possibly causing it to misbehave. Therefore, add a check for sta->uploaded which indicates that the driver knows about the station.
