qcacld-3.0: Print periodic stats only if roaming not in progress

Roaming is handled by scheduler thread which has lower priority
than kworker thread. Periodic stats are printed in kworker thread.
Since handling roaming is a higher priority job, skip printing
periodic stats so that scheduler thread can be given extra time
slot to process roaming.
