In the current implementation of ath12k_regd_update(), the ah->regd_updated
flag is used to ensure that the regulatory domain is updated only once per
radio. During MAC registration, this function is called to push the default
regulatory domain to cfg80211. At that point, the hardware state is not on
and hence ah->regd_updated remains false.
However, after commit 4c546023d71a ("wifi: ath12k: update regulatory rules
when interface added"), ath12k_reg_handle_chan_list() is invoked when an
interface is added, which in turn calls ath12k_regd_update(). By this time,
hardware state is on and consecutively ah->regd_updated becomes true.
Later, when the 11D scan completes and a new regulatory domain is received
from the firmware, the host attempts to update cfg80211 again via
ath12k_regd_update(). But since ah->regd_updated is already true, the
update is skipped.
