wifi: fix first connection security params selection
In getCandiatesFromScanResults, it will clear network candidates of all
networks, i.e. updating candidate security params does not work
actually.
As getCandiatesFromScanResults is too heavy for just a quick selection,
extracting the security params selection part and adding the same
security params filtering algorithm to have consistent behaviors with
selectNetwork().
