wlan: Fix for SAP turning ON on invalid channels for a given CC

Avoid SAP turning ON on invalid channels when a particular country
code is set in hostapd.conf due to race condition between reg
notifier and nv bin based channel initializtion during driver load.

This commit ensures reg_notifier callback is called once the
channels are initialized based on nv bin, thus updating the latest
reg domain set by the notifier callback.
