[media] gspca: Check dev->actconfig rather than dev->config 

Check dev->actconfig rather than dev->config when checking various
configuration things. dev->config points to the array of configs for the
device so dev->config->foo boils down to dev->config[0].foo and the first
config is not necessarily always the active config.
