cfg80211: lower dynamic PS timeout to 100ms

The default of 500ms is pretty high, and leads
to the device being awake at least 50% of the
time under such light traffic conditions as a
simple 1 second interval ping. Reduce to just
100ms -- it should have a similar effect while
providing a better sleep time.
