qcacld-3.0: Don't add kickout AP to avoid list if rssi < -70 dBm

During roaming tests, if an AP gets kicked out due to move away,
the driver adds the BSSID to an avoid list.
However, this approach has a drawback. If the AP later moves nearby
again, it won’t be picked up because it’s still on the avoid list.
To address this, the driver checks the RSSI value before adding the
BSSID to the avoid list for kickout roam reasons.
If the RSSI value is above -70 dBm (from INI good_rssi_threshold)
and get kickout, which means AP may have functionality issue, then
the BSSID can be added to the avoid list. Otherwise, if the signal
strength is bad below -70 dBm, the BSSID should not be avoid list
because the AP may move away, let roam logic to pick up or not based
on score value of the BSS.
