wifi: ath12k: fix regdomain update failure when adding interface

Commit 4c546023 ("wifi: ath12k: update regulatory rules when interface
added"), introduced a call to ath12k_reg_handle_chan_list() during
interface addition to update the regulatory domain based on the interface
type. While this works initially, subsequent updates (e.g., after an
interface delete/re-add cycle) fail because ah->regd_updated is never
reset.

To address this, reset ah->regd_updated before calling
ath12k_reg_handle_chan_list() to allow the update to proceed.

However, this change exposes another issue: a timeout occurs when waiting
for the 11D scan to complete, as seen in the log:
    ath12k_pci 0000:05:00.0: failed to receive 11d scan complete: timed out

This happens because during interface down, ar->state_11d is set to
ATH12K_11D_PREPARING, and during interface up, the host waits for
ar->completed_11d_scan even though the scan hasn't started yet.

Fix this by updating the wait condition to check for ATH12K_11D_RUNNING,
which is the only state where a scan complete event is expected.
