qdev: Fix exit code for -device ?

Help was shoehorned into device creation, qdev_device_add().  Since
help doesn't create a device, it returns NULL, which looks to callers
just like failed device creation.  Monitor handler do_device_add()
doesn't care, but main() exits unsuccessfully.

Move help out of device creation, into new qdev_device_help().
