mac80211: integrate sta_notify_ps cmds into sta_notify

Browse source 
This patch replaces the newly introduced sta_notify_ps function,
which can be used to notify the driver about every power state
transition for all associated stations, by integrating its functionality
back into the original sta_notify callback.
