station: Use Affinities property to change roaming threshold

Browse Source 
When the affinity is set to the current BSS lower the roaming
threshold to loosly lock IWD to the current BSS. The lower
threshold is automatically removed upon roaming/disconnection
since the affinity array is also cleared out.
