libertas: misc power saving adjusts

Browse Source 
* firmware for the CF card supports power saving
* the driver currenly only accept "iwconfig ethX power on|off", so
  I fixed what the range wext ioctl reports.
* initialize value/flags in lbs_get_power()
* get rid of unused parameter psmode in lbs_ps_confirm_sleep()
* some minor debug output tweaks
