reparent_thread: don't call kill_orphaned_pgrp() if task_detached()
If task_detached(p) == T, then either
a) p is not the main thread, we will find the group leader on the
->children list.
or
b) p is the group leader but its ->exit_state = EXIT_DEAD. This
can only happen when the last sub-thread has died, but in that case
that thread has already called kill_orphaned_pgrp() from
exit_notify().
In both cases kill_orphaned_pgrp() looks bogus.
Move the task_detached() check up and simplify the code, this is also
right from the "common sense" pov: we should do nothing with the detached
childs, except move them to the new parent's ->children list.
