[PATCH v4 04/25] dma/idxd: clear device at scan

[David Marchand]

Currently, the device object is only manipulated by the dma/idxd bus
callbacks and EAL is not looking too much into this object.

However, in the next refactoring, EAL will expect a clean object, like
when checking that the device has been already probed
(iow dev->driver != NULL).

Request a 0'd object when allocating.
