qcacld-3.0: Don't Update default country code when no country code is selected

qcacld-2.0 to qcacld-3.0 propagation

At the time of driver load, countryCodeElected will be saved as
default country code.
If Driver changes country code through userspace, driver won't update
countryCodeElected as countryCodeElected is updated only for 11d scan.
In next scan if there are no scan results with 11d country code,
the driver will try to update country code on the basis of
countryCodeElected.
Fix this by not updating country code through 11d if
number of country code count is zero in scan results.
