qcacld-3.0: Do not always reject core regulatory callback

Core regulatory callback can happan on driver reload also. User may set
country 00 when wlan is off. In that case on driver re-registration core
callback would happen. To avoid rejecting such a callback, save the driver
reload state with the platform driver.
