qcacld-3.0: Remove obsolete "change country code" callbacks

In HDD there are currenty two different callback functions which were
formerly used to synchronize country code changes with SME:
- wlan_hdd_change_country_code_callback()
- wlan_hdd_change_country_code_cb()

With the "converged regulatory" implementation these are no longer
used, so remove them.
