wlan: Initialize rssi to lookupDownRssi if no probe response

In the function get current AP rssi, the variable is initialized
with -125 if the probe response is received then later in the function,
probe response RSSI is used and updated. But if the probe response is
NOT received from the current AP then the variable takes -125 as value
and any AP rssi better than -125 looks good roam candidates and
STA tries to roam.
As a part of this change, we are initializing the rssi to the Rssi
value received from the Riva during lookup down indication callback.
