There might be latency at AP side to update TIM IE which could cause the
station to send pspoll frame even after the wakeup. If the powersave is
disabled, the nullfunc notification alone is sufficient to receive
frames from the AP. And if the pspoll frame was already sent, no need to
resend the frame till it was acked by AP.
