From: Mohammed Shafi Shajakhan <redacted> when we run high bandwidth UDP traffic and we trigger a scan, the scan state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND and SET_CHANNEL seems to be never called as 'tx_empty' is never true while running UDP traffic. fix this by settting SET_CHANNEL state when we get into RESUME state.
