wlan: Update weak zone RSSI threshold to firmware

Sometimes STA roams to new AP whose RSSI is poor but better
than current AP. For example if current AP RSSI is -85,
firmware may choose to roam to an AP whose RSSI is -83 and
connection may not go through.

To avoid this add an absolute RSSI param which will disallow
candidates whose RSSI is below this param.
