[PATCH 4/8] driver core: remove device_create_vargs

[Christoph Hellwig <hch@lst.de>]

All external users of device_create_vargs are gone, so remove it and
open code it in the only caller.

- *
- * Returns &struct device pointer on success, or ERR_PTR() on error.

- * Note: the struct class passed to this function must have previously
- * been created with a call to class_create().
