Then in ath12k_mac_op_reconfig_complete() those queues are not started because ieee80211_wake_queues() is skipped due to the check on reconfig_type. The result is that mac80211 could not deliver any frame to ath12k to send out, finally making connection fail.

This won't cause any regression because currently the only chance ath12k_core_restart() gets called is in reset case, where ab->is_reset is set so that function will never be executed. Also remove ath12k_core_post_reconfigure_recovery() because it is not needed in suspend/resume case. This is also valid due to above analysis.
