ath10k: fix idle power consumption

Browse source

mac80211 can update vif powersave state while
disconnected. Firmware doesn't behave nicely and
consumes more power than necessary if PS is
disabled on a non-started vdev. Hence
force-enable PS for non-running vdevs.

This reduces power drain on QCA61X4 from 88mA to
36mA when interface is up and not associated.
QCA988X wasn't measured.
