staging: vt6656: Power save stop wake_up_count wrap around.
commit ea81c3486442f4643fc9825a2bb1b430b829bccd upstream.
conf.listen_interval can sometimes be zero causing wake_up_count
to wrap around up to many beacons too late causing
CTRL-EVENT-BEACON-LOSS as in.
wpa_supplicant[795]: message repeated 45 times: [..CTRL-EVENT-BEACON-LOSS ]
