More correct hw flag set via ieee80211_hw_set to prevent:

Some client, like iPhone, always has frequent PS (Power Saving) state change like this:
sdr0: STA e2:72:49:82:a6:a0 aid 1 enters power save mode
sdr0: STA e2:72:49:82:a6:a0 aid 1 exits power save mode
sdr0: STA e2:72:49:82:a6:a0 aid 1 sending 0 filtered/0 PS frames since STA woke up
Now with these correct hw flag setting, the link is more stable
