[Passpoint] Handle Base64 password decode exception

Add exception handling, and use the password as-is if Base64
encoding is invalid. buildEnterpriseConfigForUserCredential
method returns void and getWifiConfig that calls it must
return a WifiConfiguration to the caller, so there is no
better error handling.
