WifiBackupRestore: Ignore configKey mismatch in backup data

WifiConfiguration.configKey() is not part of the SDK. So, we can't
enforce that all Android devices return the same config key for a given
WifiConfiguration. The configKey validation in the parser for backup
data was just meant to be a failsafe. So, it should be safe to ignore
the check.
