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.
