Johan Hovold 7c63838ea5 serdev: ttyport: add missing open() error handling
Add missing error handling for tty-driver open() which may fail (e.g. if
resource allocation fails or if a port is being disconnected).

Note that close() must be called also in case of failed open() and that
the operation sanity check is amended to catch buggy drivers.
