mac80211: improve powersave implementation
When you have multiple virtual interfaces the current implementation requires setting them up properly from userspace, which is undesirable when we want to default to power save mode. Keep track of powersave requested from userspace per managed mode interface, and only enable powersave globally when exactly one managed mode interface is active and has powersave turned on. Second, only start the dynPS timer when PS is turned on, and properly turn it off when PS is turned off. Third, fix the scan_sdata abuse in the dynps code. Finally, also reorder the code and refactor the code that enables PS or the dynps timer instead of having it copied in two places.
