The Linux kernel commit 113f3aaa81bd ("cfg80211: Prevent regulatory
restore during STA disconnect in concurrent interfaces") broke the
regulatory clearing attempt in many test cases since
cfg80211_is_all_idle() is now returning false due to the AP interface
being up and that results in the Country IE -based regulatory
information not getting cleared back to defaults.
Work around this by stopping the AP interface first so that when the
station interface receives the disconnection, there are no other active
interfaces in the system. In addition, wait for REGDOM event for the
Country IE hint after association to avoid disconnection before the
regulatory events have been fully processed.
