tty-handler: unify error handling for poller failures

We currently have a bug where we don't unregister from the ringbuffer
poller if we get an error on read(). This change unifies the
error-handling for potential failure cases in the poller handler, and
ensures that we unregister the ringbuffer poller and console poller in
all cases.
