monitor: Use traditional command interface for HMP device_add

All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one.  Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.

For device_add, that's easy: just wrap the obvious hmp_device_add()
around do_device_add().

monitor_user_noop() is now unused, drop it.
