After last transmission, the device goes to sleep earlier than the configured dynamic power save timeout. If timeout is set to 400ms, device enters into sleep mode at around 330ms since from last TX. This patch re-schedules dynamic power save timer after PSM is disabled, which ensures timeout period starts only after wakeup and the timeout variation is around 2-3ms.
