do_wait: kill the old BUG_ON, use while_each_thread()

do_wait() does BUG_ON(tsk->signal != current->signal), this looks like a
raher obsolete check.  At least, I don't think do_wait() is the best place
to verify that all threads have the same ->signal.  Remove it.

Also, change the code to use while_each_thread().
