signal: Remove superflous try_to_freeze() loop in do_signal_stop()
do_signal_stop() is used only by get_signal_to_deliver() and after a successful signal stop, it always calls try_to_freeze(), so the try_to_freeze() loop around schedule() in do_signal_stop() is superflous and confusing. Remove it. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Oleg Nesterov <oleg@redhat.com> Acked-by: Roland McGrath <roland@redhat.com>
