At present policy_mgr_check_concurrent_intf_and_restart_sap
will allocate memory for sta_ap_intf_check_work_info for each
work scheduling of sta_ap_intf_check_work. Potential race condition
would be the pm_ctx->sta_ap_intf_check_work_info is overwritten
in other thread context which is calling same function.
It is not necessary to maintain the memory
sta_ap_intf_check_work_info dynamically since only one work
sta_ap_intf_check_work is expected to run at same time.
Move the sta_ap_intf_check_work_info memory allocation to
psoc open handler and free it when psoc close.
