Fix race between pflow_output_process() and pflow_clone_destroy().

Unlink pflow(4) interface from `pflowif_list' before start destruction to
prevent pflow_output_process() being rescheduled. Also wait until running
pflow_output_process() task finished.

Problem reported and fix tested by Hrvoje Popovski.
