hurd: fix sigstate locking
It looks like _hurd_thread_sigstate used to return with the sigstate
lock held long ago, but since that's no longer the case, don't unlock
something that isn't locked.
Note that it's unlikely this change fixes anything in practice since
its current implementation (on i386) makes this call a nop.
