staging: wilc1000: Connect to highest RSSI value for required SSID

Browse Source 
Connect to the highest rssi with the required SSID in the shadow
table if the connection criteria is based only on the SSID.
For the first matching SSID, an index to the table is saved.
Later the index is updated if matching SSID has a higher
RSSI value than the last saved index.

However if decision is made based on BSSID, there is only one match
in the table and corresponding index is used.

changes in v2:
initialize sel_bssi_idx to UINT_MAX.
Combine two checks for identifying
sel_bssi_idx value for a SSID.
