src: remove overzealous tcsetattr error check
Node calls tcsetattr on exit to reset the tty to its state on program
start. Good idea in general but tcsetattr can fail for a number of
reasons and since there really isn't anything we can do about it
at that point, simply ignore the error instead of aborting with
an inscrutable error message.
Most of the time it'll be fine because the most common failure is when
the user has already logged off and there isn't anything to restore in
the first place.
