Libertas currently maintains a copy of the WPA unicast and group keys
when using WPA or WPA2. This copy is checked when deciding whether or
not to return to sleep in IEEE PS mode but the actual copying back to
priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one
issues commands that require temporarily keeping the device awake.
This patch introduces the omitted copy-back of the keys so that IEEE PS
functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for
clearing up the issue.
