unwind: call unwind_tcb_fin before printing detached message
unwind: call unwind_tcb_fin before printing detached message

captured stacktrace is printed in unwind_tcb_fin if tcp->queue is not
empty.  This should happen before printing detached message, so
unwind_tcb_fin is moved to the top of droptcb.

This is implicitly suggested by Dmitry Levin in patch review process.
