[PATCH v4 10/37] unwind: call unwind_tcb_fin before printing detached message

[Masatake YAMATO]

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 too of `droptcb'.

This is implicitly suggested by Dmitry V. Levin <ldv at altlinux.org> in patch review process.
