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.
