exit: reparent: cleanup the usage of reparent_leader()
1. Now that reparent_leader() doesn't abuse ->sibling we can shift
list_move_tail() from reparent_leader() to forget_original_parent()
and turn it into a single list_splice_tail_init(). This also makes
BUG_ON(!list_empty()) and list_for_each_entry_safe() unnecessary.
2. This also allows to shift the same_thread_group() check, it looks
a bit more clear in the caller.
