Make port close not be delayed
Drivers are dereferenced when the port is completely gone, in the operation scheduled with erts_schedule_thr_prgr_later_op. If we use erts_schedule_thr_prgr_later_cleanup_op, it may not happen for a long time and the driver can not be unloaded. We can not dereference the driver before the thread_progress_later thing, because references to the driver may exist in other threads, so the unloading of the driver may free locks held by other schedulers and whatnot.
