Various fixes to the t4/5nex character device.

- Remove null open/close methods.
- Don't set d_flags to 0 explicitly.
- Remove t5_cdevsw as the .d_name member isn't really used and doesn't
  warrant a separate cdevsw just for the name.
- Use ENOTTY as the error value for an unknown ioctl request.
- Use make_dev_s() to close race with setting si_drv1.
